I don't think the existence of Wayland means X11 is deprecated. Lots of people (including myself) would prefer the perfectly working X11 than the feature-incomplete backward-incompatible "modern" wayland
Noticeably it doesn't export Wayland to applications running underneath unless you enable an experimental flag, and half the reason for its existence is that it can be entirely bypassed by related Vulkan layer extension.
For me, the year of Linux on the Desktop was '94. It's been my main desktop at home ever since, and for wor as well the majority of time - but with some obnoxious detours.
Not advocating for 2024 (or 2025) but I still think someday it will, having seen multiple usability and feature improvements. (Not only talking about wayland here)
It's deprecated by the people who wrote it, and AFAIK no-one else has taken up the task of maintaining it. Doesn't mean you can't use it (I still use it still, thanks to said breakage), but it's not exactly thriving.
It's still seeing regular releases. It's split into modules now, but the xorg-server module last had a release in April, I think, with multiple contributors, and at least two people are issuing release announcements.
Maybe I'll consider Wayland again in a few years (though, who knows, by then maybe I'll have fallen for the temptation to write my own X server too...), but for now, Xorg works, receiving fixes, and doesn't require me to change anything else in my workflow for no good reason.
Even funnier, I have a bunch of rando computers and servers, some with friends and family with different distros...and at any given time, I'm not sure which I'm using.
(Which I suppose means that Wayland has matured a lot..finally, but still)
