If I remember correctly there was some discussion at the beginning on April where it was proposed that the 'classic' apis in 0.20 would be undeprecated in the next release and that these would effectively become the 1.0 apis, with the new apis becoming the 2.0 apis, but I've lost track of the thread. I'm not aware as to whether a final decision was ever reached.
I have this vague recollection that the 'audience' annotations (HADOOP-6668) were introduced with the intention of marking the 2.0 apis 'experimental', but I can't find a source for that.
