Here is their guide:
I see nothing that says you cannot use it to have a few spurs off the Wago, ultilising the internal bus bar to its advantage in a ring circuit. It does not even mention rings.

Nope. They will hold at over the rated current for quite some time. But you were close.
What they won't do is rupture when there is a loose connection. A loose connection does not cause an increase in fault current through the fuse.

Two solid core cables in a socket, FCU's, etc, terminals is not a good thing at all. When pushed back, stress is on the wires/terminal. I have come across many that fell out when a socket was removed - they were tight before the socket was pushed back. The screws also work loose over time with expansion/contraction. Unlike Maintenance free Wagos. Two cables are never in a Wago terminal. One flexible cable is far superior into the rear of a socket/FCU etc. It just is.
I never suggested using Wagos in appliance grids. Another poster pointed out the clustering on a ring, or radial of a dedicated appliance switching module.

Now that is the first post of yours which I agree with. Well, mostly anyway.

My initial point was that the internal bus bar in a Wago can be used to take off a few Spurs from the Wago, when on a ring circuit. Below: the bus bars can be clearly seen on a three connection Wago (left) and a four connection In-Sure connector on the right.
Ring in and out of the end connections, making the bus bar a part of the ring, then two spurs off that, using the middle connections - all legal.
It makes NO difference AT ALL whether you use the outer position or the one next to it. The connector is rated for the specified current. 5mm of copper makes virtually zero difference.
Yep, I agree that sometimes connections can work loose if people are careless. Always push the socket back, then re check the screws are tight before final fix.

That is time and effort. Then there is the prospect of the terminal screws loosening over time - happened on one of mine, an FCU supplying a dryer. The ring's current runs through those socket terminals, which is not a good thing.
Having the ring run through a maintenance free Wago in the back box, with a felxible cable into the sockets from the Wago is a far superior solution. The Wagos connections take the current load around the ring, not working loose over time. The ring's current flow is kept away from the socket's terminals. Current only flows through a sockets flex wires and terminals when the socket is switched on drawing current. Superior, safer and quicker solution.
In Germany they sell sockets with Wago connections on the back, making matters even easier and safer.

Each spur has its own connection on the Wago, taken off the internal bus bar, not taken off one connection.
Look at the photo.

Its not a busbar, its a connector with multiple cable outlets.
I know you keep referring to the solid continuous piece of metal inside of the wago as a busbar, I get it, it even functions like a busbar. But its not a busbar its a connector, thats it's purpose and thats the standards its been tested too. If you want to convince me that wagos are busbars then your need to show us the relevant BSI documentation.

@AJshep please be careful not to get sucked into this thing now! By condensing each point into just the width of one port on a Wago 221, it seems the OP managed to wire up an RFC smaller than its own Schwarzschild radius and it collapsed into a black hole. This is now pulling cables, sockets, junction boxes and possibly electricians too, across its event horizon. As the materials accelerate away from us, the Lorentz-Fitzgerald contraction makes cables look like busbars and busbars look like single terminals. Due to gravitational lensing it is no longer even possible to distinguish a ring from a spur.

That's a bit bigger than 5mm. But is it a single point?
Multiple pints- nice!
Well if we're going to splice the ringmainbrace, mine's a Scotchlok Wiska.
I like plenty
but does plenty like you? you could get a room.

A room with a bar. And a bus. Way to go!

Spotted this video on Efixx and it reminded me of this thread:
MK Logic Rapid Fix.
MK Logic Rapid Fix.
They are a great idea but at 29.99 each in screwfix I dont think I'll be sampling them

That price is for a box of 5, although £6 each is still a bit steep.
Actually that is a brilliant idea!
Yes, a little on the pricy side but you can see it would lead to time-saving and probably far fewer problems of poor ring continuity in the future.
6 quid each isn't too bad but still expensive for a socket. Hopefully in time they become more common and come down in price
Fitted some 32A triple pole sockets a few years back with push fit connections. Lifted a plastic pin pushed conductor in then pushed pin back down. Wasn't sure about them but they gave no problems.
Looking back at original posting to see what its all about, in ~13 JSJW quotes a method for terminating to socket outlets.
I use wago's to terminate for testing at first fix stage but then disconnect and terminate the single core conductors straight into socket terminals for second fix (re-using the wago's eleswhere).
I think (although never tried it) phaffing about with flexible conductor (extra cost and time) which 9 times out 10 would need a ferrule to terminate correctly would be less efficient?

They are £5.99 at Screwfix. When other makers get on board, with single, FCUs. etc, expect them to drop substantially in price, as did screwless downlighters.
They are well overdue. They still do not eliminate Wagos at the back of backboxes for ease of 1st fix testing.
I do not know what max amps the connections on the back of these MK Rapids is. I assume 32A.
Some 4mm radials go over 32A. So best fit a ring in that case.
Nevertheless, a great advance. We are still about 40 years behind Denmark, Germany, etc, where screwless sockets are the norm.

Not UK 13A 3 pins. What were they?
It is quicker leaving in the Wagos.
30 sockets, which is normal in many homes, can have 90 flex tails. Easy and much quicker when the tails are fixed to the sockets on a bench. Then a sinch in pushing them back into the boxes, with no stress on the terminals.
Also, no terminal has more that one conductor in it. Current only flows through the socket terminals when that socket draws current.
The sockets terminals are not used as junctions, carrying the final ring's load. The superior Wagos with one conductor in each slot, carries the load.
Much superior method.
Safer all around.
Quicker to install.
Eliminates stress on conductors and screwed terminals also.
It can knock a day off an install.
Cables all tested on 1st fix.

Sometimes known as Commandos.
Well that is an MK brand name.

Going "Commando" is something completely different !
