Just endpoint cps (IIUC).

Beta sounds like a good idea given the amount of change in 0.96.  Could
make one soon, as soon as we branch.  I could take care of this if folks
like the idea.  Call it 0.96.0-beta?

Not mad about carrying contribs in hbase.  We've been there.  No problem
pointing/advertising dependent repositories and doing anything in core to
facilitate dependent/supporting work but would rather not carry the stuff
in core; in general contribs start to become a drag on core dev.
