I've almost suggested the same thing while looking at a couple of the issues Patrick has raised. Too much has changed / is still changing between the hadoop 1 and 2 APIs. It's pretty much impossible already to cater to both and I don't see the situation improving. We already produce 2 artifacts, so we might as well produce them from different branches. The end result for the user will be no different.
Big +1 from me.
