Is XAA still supported in recent and future xserver?

Agreed that a replacement is needed before removing anything.  I think
we're all in agreement there.

I'm not necessarily arguing for dumping XAA (I don't know enough for
that, hence my questions.).  I'm just from the school of thought that
if two things are redundant, get rid of one of them. Less maintenance,
confusion, duplicated effort, ...   If EXA could be made to be
performant on that hardware, I think getting rid of XAA would be a
good idea, for the pre-mentioned reasons.  If it can't, then end of
discussion for me.

How does Gallium3D and cairo fall into this argument?  Are they
alternatives to XAA and EXA? (again, I'm still learning.)
