I hate: Programming Wayland applications

Article note: ~15 years into "The Xorg developers have determined X11 is an unmaintainable mess of poorly-fitted extensions and anachronistic API designs, and have decided the successor will be... an API made entirely from an assemblage of poorly-fitted extensions, that will start to look anachronistic before it reaches feature parity." (I daily-drive a KDE Plasma on Wayland session for the last few years, most of it works, but that doesn't mean it was a good design. The papercuts, especially around input plumbing, are obnoxious and obvious.)
