The thing that you have to remember about Xwayland is that it is Xorg. It just has a Wayland DDX[0] on the back end rather than a device-specific DDX or one that talks e.g., directly to the modesetting driver. [0] Device-Dependent X, i.e., the bits of X that talk directly to the display. Contrasted with Device-Independent X (DIX), i.e., the bits that do state tracking and protocol communication with clients.
