Yes and no... from our CDH perspective, if 0.94.x is out by the time
we need to get CDH4 "GA", then we'll skip from 0.90.x in CDH3 to
0.94.x in CDH4, and hence we need an upgrade path. So if upstream
doesn't support it, we'll have to hack it in as a CDH special. That's
fine -- but if there's no change that forces us to break
compatibility, why break it?
