> wayland _should_eventually_ be able to completely fill the role that X11 currently fills.

Which X11 features are still missing? Does Wayland support X11's seemless remote multiuser sessions already?

I've googled around and found this fresh message from April 2012:

"... X11 support on Wayland. It's basically ready to go, but window management is implemented only as a hack right now."

That doesn't sound good. It seems that Wayland will have a hard time to replace X11 in the next decade. Currently I see no reason why I should switch.
