Remember that the core protocol is not only for GL-enabled servers
or overlay hardware. A completely software-rendering compositor on a
dumb framebuffer is also a possibility, although not implemented yet
AFAIK. There have been some ideas about a pixman-based compositor
instead of GL ES 2.

Think about wanting to run Wayland apps on a machine without any
graphics acceleration hardware.
