You will never get 2 electricians to agree on everything all of the time, different electricians do things different ways and as long as both ways are safe then there shouldn't be an issue. sometimes as sensible people we just have to agree to disagree.
This subject has been discussed multiple times over and always gets mixed opinions. At the end of the day each method has advantages and disadvantages.
Either way the circuit is going to function exactly the same and it is down to the electrician designing/installing the circuit to do so how they see fit.
I am sure there are much bigger problems going on in the world than neutrals at switches to be honest.
If it is safe and complies with BS7671 then what actually is the big issue?
