That's plain wrong. The window provider is responsible for input event and lifetime of the surface. Rendering is the job of the display.

WTH are you on about?! You don't get to choose what display module is used. If you provide a Wayland type surface you have to follow the general conventions and the specific conventions for the Wayland type.

Breaking any display module is not allowed, and certainly not the reference implementation (SHM in the case of Wayland).
