I think hn/reftable is very much ready for "next", and it would be good
to get a strong start at the greater "reftable" topic this cycle, which
ab/refs-errno-cleanup is also a part of.

As noted in a recent thread[1] I've got pending patches on top of it
that go further in closing the gap between hn/reftable and eventual full
in-tree integration.
