Surely the one thing we have learnt over the last 4-5 years in this project is that we cannot
make too many major releases. Notice how long hadoop-0.20/hadoop-1 lives; the same will happen
with hadoop-2.x. Look at Bobby's message on this thread on *-dev lists:

Each major release is a *lot* of work and is, subsequently, an opportunity where incompatibilities
at various levels creep in - our users are not well served by this.

So, it's a  fallacy that we can and should make major releases per feature.
