I think you're mixing up two different concepts: support for running X
apps and support for running X as the system display server. As I
mentioned before, my guess is that GNOME will only work with Wayland
as system display server within a year or two. Similarly, I expect
Unity to only work with Mir as the system display server for either
14.04 LTS or 14.10. Developers are not switching to Mir or Wayland for
theoretical minor features, but to finally move past long-standing
issues with the X stack that impact users.

Obviously everyone will still support running legacy X apps for at
least the next few years.
