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.
