Good, sounds like what I was saying about having a11y features in the normal
compositor instead of a a11y-only one like gnome-magnifier.   But for it,
that still leaves the questions of:
  1) Is gnome-shell ever going to port to Wayland or only support X11?
  2) Does Wayland provide everything gnome-shell needs to provide those
     features?

Wayland changes the way compositors integrate with the window system,
so work would probably be needed to make gnome-shell work well with it.
