Wayland and Fedora

As you may have seen, I have proposed that GNOME should move towards Wayland. We hope to have experimental Wayland compositor support in GNOME shell in the fall, and a complete port of the GNOME desktop a year from now. See  for more details.
What does this mean for Fedora ?
I don't think this will affect the rest of the distribution in a majorly disruptive way. In particular, it won't force other desktop environments to move away from X. gdm will learn to launch Wayland-based sessions, but it will still be able to start X-based sessions. X applications will continue to run as they used to, including remotely. And GNOME applications will continue to work under X.
Here is what I envision:
- wayland + weston (the reference Wayland compositor) are available
- gtk3 and clutter are built with their Wayland backends
- it is possible to test individual GTK+ applications under weston, by setting GDK_BACKEND=wayland
- will have a gnome-shell that can run as a Wayland compositor
- gdm can start Wayland and X sessions
- there will be an experimental GNOME/Wayland session in the session chooser (probably in an optional package)
- most GNOME apps can run under Wayland
- the X-based GNOME will still be the default
- the Wayland based GNOME will be the default
- a GNOME/X session will still be available
(of course, all of this may change, depending on how the porting works out).
