I'm a little concerned that 'silence means violent agreement', because
I'm still a bit worried about the cost, but I guess the restricted
nature of patches to the release series should mean we don't change
things too franticly here. 

In terms of what we promise to our cluster users, should we just promise
and test an upgrade from the exact previous version (but deliver broader
compatibility in practice)?

Finally, how are we going to mark and version these structures, so that
it's unambiguous as to what structures are part of both the long-term
and short-term ABIs here?
