There's another useful analogy with CXF. If a group of people showed
up with a proposal to make a brand new fork and launch on it, I for
one would politely ask them why they feel the need to diverge, and I
might hear something that disturbed me.

However, that's not the situation here. A community of developers
formed inside of a set of institutions that did not allow them to
interact with HBase. Now they exist, and their code exists, and their
rules have changed. They propose to join us. My reaction? "Wonderful!"
It may be that, over time, this group and the existing HBase group
will discover a commonality of interest and goal, and coalesce into
one big happy community. It may also be that differing priorities
won't lead in that direction.
