wl_surface.damage can be implemented in a non-optimal way by the compositor
(e.g. by always damaging the whole buffer).
Having two requests makes it complicated for the compositor to handle damage,
making it necessary to transform one into the other's coordinates.
Moreover, integration with wp_viewporter is tricky.
