> X11 is not actively developed, a fork is.

That's a weird framing.

Original X was forked as XFree86 and included in all the major distributions.

Xorg was a fork of XFree86, and subsequently included in all the major distributions when some devs/sponsors wanted to take it in a different direction.

XLibre — if that's what you are referring to — is another fork in a long line of forks.

So when you say X11 is not being developed but a fork is, which one are you referring to?

Weird framing is injecting decades old semantics to an issue most people already understand as X11 vs Wayland. Since everyone has defaulted to X11/Xorg prior to Wayland, it is known as xorg and x11... Not that fork of "XFree86".

X11 and Xorg, as we know it, are not in active development but maintenance mode. They have planned to wind down for a while, and this has been old news for over six years now... The code rollback and freeze inquiries should've signaled people off.
