That's basically the same issue as multiscreen, i.e. something that took
decades in Xorg to settle :) (and still bogus at times, I easily break
my laptop when unplugging/plugging screens, put it to sleep mode etc.)

Yes it is.

Or use a multiplexer like I mentioned before, the question being how
one is supposed to request the switch: a keyboard shortcut, some
xrandr-like-command, etc.

Yes.
