a) Not only. On client side all objects are QObject to ensure that we can emit signals in future (in case the wayland interface emits events it needs a signal)
b) I don't get the question.
c) yes questionable. The idea is to have an interface which allows to integrate with low level Wayland calls. An example could be wl_compositor which can be retrieved through the Qt QPA. If one would want to create a Surface with that one, one would need the low level calls. It might not make sense on all wrappers, but for API consistency I decided to add it to all interfaces.
