Apparently you only want wayland based DEs and considered the argument to be over for everyone.

How wrong were you. Lot's of people don't want to use wayland until it reaches a certain feature-complete maturity. I for instance have again put it off for another year and won't consider running a wayland only DE at all for the forseable future since it breaks too many things for no good reason and I need to be able to switch back to X11 if needed. I use my pc for for work, not just as a troubleshooting toy.

Taking the topic into account of people moving from old school Windows 7 to this Windows-like distro, these people will probably be more pleased by X11 (hassle free screen sharing, global shortcuts) vs the wayland "in theory it is great and modern but in practice there still are way too many incomplete and missing pieces" situation.
