For all y'all saying "I'm still using X because Wayland isn't ready"... this is your reminder that X is DEPRECATED. The entity committing resources to maintaining it -- Red Hat -- has abandoned it and committed to Wayland only going forward. Unless another entity steps up with funding, X is doomed to bit rot and Wayland is the future. The responsible thing to do is to suck it up, file bug reports, and write code and/or documentation to improve the Wayland side of things because that's where the money and developers are -- period.

(And before you slag off Red Hat, remember that they are the Atlas holding up the entire Linux userland ecosystem for the past couple decades or so now.)
