This. this is why I've been a bit confused on folks not wanting to
invest the time in getting multiple major branches working correctly.
With my "Hadoop community" hat on, I see that we struggle with
maintaining multiple maintenance lines just within 2.y and I worry how
we're going to do once 3.y is going.

With my downstream "HBase community" hat on, I'm pretty sure I still
need there to still be 2.y releases. AFAIK the HBase community hasn't
made any plans to e.g. abandon Hadoop 2.y versions in our next major
release and we'd be very sad if all future features we needed added to
e.g. HDFS forced our users to upgrade across a major version.
