The idea has been discussed, but I don't know of anyone actually making
any effort in that direction. And honestly I'd prefer if they didn't.
Xorg so deeply assumes that you're talking to physical hardware that
making it _not_ do so requires intrusive changes. Xwayland began life
as an Xorg driver, and that ended up being kind of a bad plan. I don't
see why dummy/nested would be preferable to Xvfb or Xnest.

Xvfb is as maintained as any other server we build, certainly I test
against it infinitely more often than against dummy.
