It is a damn shame that tools like xdotool (automation) and sxhkd (global keybinds) are impossible to recreate under Wayland.
Not only that. A11y is also quite hard. Tools that are simple to implement thanks to good a11y apis - for example on macos, the tool rcmd or homerow - are super hard to do in Wayland.
Not literally impossible. You just need to write your own composer!
wdotool exists, and global hotkeys are a thing under wayland, but is desktop dependent. KDE allows it by default, Gnome can be made to do it as well with an extension.
I'm using Sway right now and I have key binds. Not sure why you think that's impossible.
Not impossible, it just needs to be implemented at a different layer. The compositor needs to expose some API for global hotkeys. For example, I found this with ~2 minutes of Googling: https://wayland.app/protocols/hyprland-global-shortcuts-v1
