I agree that it isn’t a great metric for, like, how good the desktop environments are in some overall sense. I’m just saying it has enough users that it isn’t some niche thing where a ton of bugs can easily hide.
So does Xorg. I actually switched my spare PC to Wayland (default Ubuntu) recently because Xorg (on Linux Mint) kept going black whenever my monitor would sleep/wake. Nothing too fancy, just an HP tower with Intel CPU and Nvidia GPU.
Idk what's even different between them, it was just obvious that I was in the non-default / minority of users territory, so I got out.
