I understand the urge to slim the server down, but deprecating XAA isn't the way to do this. In order to deprecate something, there needs to be a replacement. As others in this thread have stated, there is hardware for which EXA is slower than XAA or does not work all together. So EXA is not a 1:1 replacement for XAA. I can't see why being able to remove XAA (which would be the intended goal of deprecating it) would help anything anyway. The xserver can already be easily built without XAA.
