X11 will not wither overnight. There are still things which are very dependent on X11. Remote connections comes to my mind, for example.
Lastly, not all distributions are followers. Debian (testing at least), installs Wayland by default, but not enables it. It's installed on my system for a couple of years now.
Thankfully I don't have to, I want shiny new software thanks.

Nobody uses them any more.
That's a choice. I prefer uptime more, for example. I use boring technology to create fun things.

You should follow X2Go users' & OpenOnDemand mailing lists. They're very heavily used by some significant groups (e.g. scientists).
There is also a VNC server for fullscreen sessions (only supports wlroots compositors for now): https://github.com/any1/wayvnc
Thankfully enough people have made it for Fedora to be convinced it's a good idea. Other distros will soon follow (as always) and X11 will wither. Finally.
