I don't know about all of those. Not sure if you downvoted me, in which case you might have the predisposition of not giving a shit. In which case I'd be most happy to oblige.
As for the technical implementations / shortcomings, I... don't really care about it. The reason I didn't use Wayland before was because things didn't work. The reasons why I don't use X11 now, is because things occasionally stop working. The reason why I still sometimes use X11, is that unless I do so, some specific software doesn't work. That's the frame of mind I have, and I don't have any allegiance or vested interest beyond that. You seem to have that, and that's great. Caring about the technical details has my respect.
So as for the stuff you mention that is directly user-facing:
Screen recording used to be a problem, haven't had that issue recently. OBS records my screens and part of it, just fine.
Window sharing like you could with X11 with ssh -X is amazing, and doesn't work, but it's been about 15 years since I used it.
Crashes that completely freeze my computer. Doesn't happen in Wayland. Happens in X11 (it's not a kernel panic, but whatever it is, I have to reboot, end result is the same to me).
Have had no issues with any of the monitors I own.
Global hotkeys work, and have always worked, for me. If it didn't, I simply wouldn't use Wayland, as a lot of my workflows surround tools I have built and trigger with global hotkeys.
Sleep mode, I don't use. Is that the same as Hibernation?
I don't use a single appimage, but I downloaded one to try now, and it worked fine.
What is redshift?
"Windows can't raise themselves or keep themselves raised", does this mean to request to be in focus? I'm curious which programs benefit from this.
sudo is insecure by default in Wayland? How come? I'd be interested to know how it has anything to do with wayland/x11. unless you mean GUI applications executed with sudo, not having access to wayland stuff?
