The biggest thing I can think of is that X11 is more flexible when it comes to specifying custom resolutions; which some people use to output 240p on CRT TVs for emulation. AFAIK, there is currently no real equivalent for xrandr on any Wayland compositor.
I’ve also noticed that Grsync’s password prompt is broken on Wayland. Thankfully, it has a feature that lets you preview the command it’s about to run, so that you can copy and paste it into a terminal.
Being a KDE user on EndeavourOS, I use Wayland everyday. I switched over a few years ago for Waydroid, but now X11 isn’t even an option for me with the current release of KDE.
It’s not about creating global hotkeys, it’s about registering them from a running program. There is nothing preventing you from creating a compositor-level keybinding, but an app cannot do that unless it figures out what compositor you are running and then handles the configuration for each and every compositor in existance.
Ah, okay then. Might be worth a try.
I wouldn’t worry about supporting every compositor in existence. Ideally, the Wayland spec would be unified, but it’s not.
I feel like if someone created a compositor with an extension for that feature, it’d eventually become popular enough that people would start implementing that extension in other compositors.
