Yet another, "well, yeah, technically it has security ramifications, but I'm not admin'ing any multiuser machines, so I'm not losing any sleep over it" bug.
I think it's still valuable to document these things so that the users who insist on sticking with X11 can receive a healthy dose of this (replace diapers with vulnerabilities) when the proverbial shit hits the fan and it becomes as hackable as Windows XP
Well, freedesktop.org is now focused on Wayland (Xorg is not getting HDR, new synchronization protocols, or proper VRR (unless through XWayland), while Wayland is). RedHat RHEL marked Xorg as deprecated last year and will not even support it by next year (RHEL 10). KDE and GNOME also default to Wayland.
It is. That's why Wayland is being pushed so hard, it's a codebase that's actually maintainable, with hopefully some more modern design and engineering principles.
