The key point your missing is that you're not using wayland. You're using a wayland. Each wayland is very different from the others in terms of features because they aren't implemented internally as a wayland standard, each wayland picks and choses between various external libs to try to reach normal desktop feature parity for things like keyboard/mouse/input device support (ie, the libei wars: some waylands use it, some hate it and never will). There's no such thing as "wayland". There are only various different waylands. A person can have an experience with X11, there's standard reference features all X have. But your experience with a single wayland doesn't really give you knowledge of how waylands work (or don't work).
