Many things in the list are niche concerns, counter to the design of Wayland or are actually solved today. But regardless the beauty of Linux is choice. I hope X11 and non-systemd distros stick around for the few that have those niche concerns. I think a lot of frustration from these folks come from the fact that they wished they weren't in a niche and better served by more maintainers, but that ship has sailed. For mainstream use-cases this has mostly been a good thing.

I've been fully on Wayland for around 10 years now. I do not see literally any issues in my day-to-day use. Of course I don't use nvidia, why would I use the most linux-hostile GPU vendor out there?

In fact I shudder when I remember the endless hacks I had to go through to have xorg stop tearing and/or get my C-states low enough so that I have more battery life. Things that are all way more important than literally anything on this list.
