I would like to suggest - for your views!

The circuit cables attached to a terminal block that is a part of the back
box. The switch or socket would be connected to that block with a fly lead
that would be an integral part of that switch / socket with a Wago type
connector.

Any sympathy for this idea?

I cannot see that coming but there is potential for Wago type connectors on double sockets. I have seen a video of someone who mocked up one just as a demonstration. Light switches, single sockets and other 1-gang accessories could be problematic to fit in existing back boxes and that is where the real problem is in backward compatibility.

One common issue I do see is the copper wire deforming in a ductile
manner under the screw, which is a form of stress relaxation

The wires are no longer under the same level of compression at the time
of installation, so that would be one benefit of using wago style
terminals in place of the screws.

Heck, the same idea could be applied to RCBOs/MCBs current carrying
capacity permitted on the output terminals.
