It makes sense to not hold up an RC since they don't affect testing of
functionality. Prior releases have ultimately gone out with doc issues
still outstanding (and bugs) though. This doesn't seem to be on
anyone's release checklist, and maybe part of it is because they're
let slide for RCs.  Your suggestion to check-point release status
below sounds spot on; I sort of tried to do that earlier.

Makes sense if these are all getting translated into Blockers and
resolved before an RC. It's the simplest mechanism to communicate and
track this in a distributed way.

"No blockers" is a minimal criterion for release. It still seems funny
to release with so many issues targeted for 1.6.0, including issues
that aren't critical or bugs. Sure, that's just hygiene. But without
it, do people take "Target Version" seriously? if they don't, is there
any force guiding people to prioritize or decide what to (not) work
on? I'm sure the communication happens, just doesn't seem like it's
fully on JIRA, which is ultimately suboptimal.

Yes, that's great. It takes the same effort from everyone. Having a
green light on a dashboard at release time is only the symptom of
decent planning. The effect I think it really needs to have occurs
now: what's really probably on the menu for 1.7? and periodically
track against that goal. Then the release process is with any luck
just a formality with no surprises.
