X11 was the only standard prior to Wayland.
GNOME is dropping X11 in a short time.
KDE's telemetry even five months ago showed 80+% of (that portion of) their userbase uses Wayland, and they plan to drop X11 once they have a concrete set of problems worked out.
Hyprland and Sway run Wayland exclusively.
Cinnamon, MATE, and Xfce are working on Wayland sessions. Cinnamon's is there but, I think, still experimental.
Budgie is working to go Wayland-only.
There's no sign that Wayland will stop improving from a state that's arguably already much better than X11.
X11's actual maintainers barely want anything to do with it beyond bug fixes, and the only person who wants to "innovate" it via a fork is a bigot and a fucking moron who doesn't know things you learn in CS 101.
X11's maintainers are majorly involved in developing Wayland and have been since the start. This is their idea.

It seems like it went from "Situation: there is one standard" to "Situation: there are two standards developed by largely the same people with one set to replace the other", and then soon: "Situation: there is one standard and one translation layer kept around for a decade or so for compatibility."

Not every single time someone tries to make things better is this xkcd relevant; this had nothing to do with unifying standards and everything to do with superseding one.
