Its becoming more common and most desktops are beginning the long process of switching to Wayland as the default. I use gnome Wayland on opensuse tumbleweed but I don't remember, or think, it was default.
Yeah. And keep in mind that a lot of the "nvidia issues" are a mix of outdated information and just the general tribalism over ideological differences a lot of (generally newbie...) linux evangelists have against nvidia. It is far from perfect, but it honestly feels no different than any other linux experience: Some stuff is going to just not work and you'll either spend way too long debugging it or learn to not care. Which... is not dissimilar from windows or mac.
The main gotchas I've found is that some applications and games with native versions may depend on x11 specific features. Starsector is a notable example where the easiest solution is to run the launcher once in an x11 desktop and then never care again.
I'm sorry, but your assertion that those who are upset with nvidia are mostly "newbs" is nonsense.
Plenty of more experienced users despise nvidia as well, and they have done immense damage to the Linux desktop.
In fact I would argue the opposite, given the proliferation of distros focused on new users which specialise in making nvidia drivers easily accessible for these users.
