For laymen, like me, this is an unpenetrable labyrinth ;) although I try to
catch-up as you can see.

True, but my concerns were about being taken over by progress and KDE
developers not being aware their efforts cause harm in "the field"

Besides, there is a warning when enabling EGL in Compistor System Settings,
but it only warns about disabling compositor if EGL is not available. I
think a warning about maturity and stability would be appropriate?

You make it sound like it is the (lack of) maturity of Intel's driver
that's responsible for my experienced plasma's instabilities?
Is there no chance of it being buggy EGL implementation in plasma?
