GPU drawing can still be faster than on the CPU, and you can do that with Wayland, by directly opening the DRM device (/dev/dri/render*) and sending the rendering commands directly to the GPU. This is how Mesa implements OpenGL on both X and Wayland. The X way requires you to send XRender commands to the X server first, and then it sends them to the GPU. This was already too slow (hence the already existing bypass for OpenGL) and Wayland just extends that idea to all rendering.
