Would gles1 be sufficient to run a Wayland compositor, I'm guessing probably not..?
If you can find a Wayland compositor that is written to composite with GLES1, that's all you need from the "Wayland side". (Yeah, this has nothing to do with Wayland per se.) Compositing in itself without any effects is very simple, as long as you get the textures up.
Or, if you find a Wayland compositor written to use desktop OpenGL for compositing and does not use features your GL driver does not expose, that's good too.
Is desktop OpenGL accessible from "EGL_PLATFORM=drm"?
To answer my own question, it seems that is possible. I wonder if it works with mutter/cogl???
Absolutely nothing about Wayland limits your choice of the GL flavour - even more so as the compositor is not running *on* Wayland.
Also, the question of running GL apps on Wayland is a whole another matter. There used to be a common misconception that Wayland had something to do with only allowing GLES.
Finally, there is the option of software rendering for composition...
Well, considering I was wondering about running Wayland on ancient hardware, perhaps software compositing wouldn't be ideal! ;-)
