There isn't. I don't think there's any intrinsic difficulty in doing so,
other than the buildsystems and X's own unstable driver API.

I'm not questioning the fact that it would be preferable to provide
compatibility. But that compatibility doesn't come for free - someone
has to implement it, and when your developer base is almost entirely
made up of people who are doing this because they find it fun and
interesting rather than because they're paid to, who's going to do it
and what functionality is going to be delayed as a result?
