Redhat does a lot of testing/patching with Xorg Server.
most of the people who was working on Xorg Server moved to Wayland a few years ago, Ubuntu and Debian have been Defaulting to Wayland, on the main Desktops, and Desktops are dropping Xorg Server support in Development, this is not just Redhat.
No Patches and No $$$,$$$,$$$ = Xorg server dead. if you want to pay 15 to 20+ Software Engineers/Testers to work on Xorg Server got for it.
FreeBSD has Wayland support to.
Even the Xorg mailing list is mostly dead, many of the Xorg Server Dev’s moved on, XWayland will be long lived.
and last i was there for all the Crying about XFree86 to I’m old.
