Actually, that's exactly one of the major reasons put forth for switching to Wayland. The very comment you replied to quotes it:
>>> a major maintainer of X server telling you he's not going to work to maintain the project anymore
If the project ends up truly unmaintained, it really would end up disappearing from the face of the earth as the platform under it (the hardware, the kernel, etc.) changes to the point that it becomes non-functional.
X disappearing from the face of the earth would be a great thing for wayland, because people would be forced to fix the remaining issues.
I’ve seen this happen multiple times with replacement systems: as long as people can escape back to the old system the new one remains rough around the edges, but once the old one is turned off the new system rapidly improves to production level quality.
The issues can’t be ‘fixed’ in the Wayland protocol, but have been addressed by individual compositors and libraries like wlroots. The difficulty is not in building a decent Wayland desktop from scratch (GNOME, Sway and ChromeOS have all done this), but in rewriting X11 window managers, screen sharing apps and automation tools that perform functions that are the compositor’s responsibility under Wayland.

The kernel has a pretty strong backwards-compatibility stance, so you'd need to wait a long time.
Nobody stops you from running an outdated and insecure distribution to use X11 (in this hypothetical future). Nobody stops you from patching X11 to support newer interfaces.
If you want to stick with X11, you can. Nobody urges you to upgrade.
