I've been using Wayland as my...whatever it is (display server, window manager, thing) exclusively for the last year or so. I did hit this bug https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1... but it was (eventually) fixed.

As for those other things you mention (xprop, etc.), I don't even know what they are, so I assume I've never used them.

I think you underestimate the degree to which desktop Linux users just want a working system with sane defaults. Maybe you personally value having all the knobs to twiddle, but I'd suggest you're an outlier.
