It is in hard maintenance mode though (and 3 years is not that long). Although X11-the-protocol isn't going anywhere, X11-the-server has no real future. Mind you, "maintenance mode" does not mean "abandoned", but it also means that it's not really going to evolve and improve - it will effectively just stay where it is for people who may still have to rely on it. Changes in Xorg codebases are very rare these days and most of them are related to XWayland.
Nobody is going to depreciate x11. It's been 3 years since Red Hat said x11 is going into "hard maintenance mode" but here we are.
I'd love to be optimistic about the adoption of Wayland (I'm now using it myself on my gaming rig), but I have zero reason to believe that everyone will eventually use Wayland. x11 is simply more finished and robust.
