It will as soon as I (or someone else) find a bit of time to implement
it.

I meant the entire thing. I don't think we should care too much about
which actual bits each driver supports since that can even depend on
which plane is used in some specific platform. So we should just
document all the possible bits, and if you want you could add a note
stating that a specific driver/platform/plane may not support all of
them.
