Yes - Intel could but why should they take care about something which get only used in a single distribution - for the said ecosystem where Canonical played a game and lost it?? Canonical have done already great work of fragmentation of said ecosystem and it seems they do not care as they live in their Ubuntu universe but the rest have not forgotten how this Mir debacle started - X11 have layed the foundation for Wayland years before - in their hard work in X11/Mesa and carefully engineering and the road was and is: X11=>wayland. Intel made a statement and I think the decission of NVidia/AMD will not be different as Intels one.
