I know I have used it since Fedora made it default in 2016. I think I actually used it a while before that, but I don't have any thing to help me pin down the exact time.
Since I only use Intel built-in GPU, everything have worked pretty well. The few times I needed to share my screen, I had to logout and login to an X session. However, that was solved a couple of years ago. Now, I just wait for Java to get proper Wayland support, so I fully can ditch X for my daily use and get to take advantage of multi DPI capabilities of Wayland.
