Wayland, and the entire Linux Window manager situation seems like a massive mess from the pov of an outsider, a widely used, stable and open-source app that can bypass this unnecessary complexity could be a great example for other apps to follow
Not sure what you mean about bypassing complexity, but reinventing the wheel might be a waste of time unless you really need it.
For example Wine supporting Wayland had to do a lot of relatively direct work with the protocols and it made sense there, but otherwise you can just use SDL or something similar or even a higher level toolkit like Qt.
Haven't fully digged into it, but firstly, the executable is tiny, source code seems sane, performance for average sized projects appears to be better than existing solutions, and also some interesting features such as viewing texture/image buffers within the debugger
It's still in alpha so not that big a deal. Vast majority of users will be on Windows, so perfect for identifying bugs quickly, and then Linux should hopefully get a stable port soon. Personally code primarily on Windows but a good GUI debugger would make me very seriously consider Linux as an option to get finally get away from Microsoft
