The manufacturing of the latest technology will always have 2 speeds those that will have it at any cost and those that will buy at a price that suits their budget. Those who pay the at any price for technology will always have an advantage over the latter as generally when it becomes viable to the masses it is already old technology and the manufacturers are just making the most out of it they can
That is a true statement for the private sector, but it's not always the ones that can afford the latest gadgets that make the most of them!
Regarding containment, always follow guidelines for installing cabling and then add a little space for additional cables, i.e see attached photo of 3 x cat7 lines in 20mm tubes...they just fit.
So if installing cat6A and above allow 25mm tubes for 4 x data at least, and better 32mm....
