Yeah, except what happens when the apps and toolkits you use drop X support because they consider X a dead end? What will you do then?
This is NOT a hypothetical. Projects have dropped ALSA support and adopted a policy of PulseAudio or GTFO -- and ALSA has more commitment to its long-term maintenance than Xorg now does. And I suspect the next phase will be Wayland maintainers putting pressure on toolkits to drop X support, much like Lennart pressured the GNOME community to hard-depend on systemd.
At that point the Wayland ecosystem is hopefully mature enough to make the switch less painful than it is now. I don't see anyone saying they'd rather toss their computer in the garbage than ever use Wayland, just that it doesn't currently meet their needs.
