Mesa provides the extension EGL_EXT_platform_wayland[1].
This extension allows the user to get an EGLDisplay from a Wayland
display connection.
I think for now I'm safe assuming the default EGL display will be used
for rendering.

That is supported under MESA using device_id in the configuration.
You can make any application render by default with a different
driver/gpu. I think the application is still able to enumerate the
devices and change them if they want so.
Thanks for the answers, they clarified a lot of stuff.
Kind regards,
