In KDE, you can rebind the keybinds for anything, it’s under system settings in the keyboard section, I’m not really sure what you’re talking about. You can add custom ones to run any command, too, if the app doesn’t register a keybind, so you could, for example, send a dbus signal to the app. The way it’s done in wayland is different, but KDE supports all the stuff you mentioned in wayland from what I can tell.
