If someone is actively working on it, they could just stick a comment
on the issue, possibly with a mailing list posting.
With a simple "in progress" flag you can end up marking things as if
someone is working on it, but then they go off and do other things.
If you just have a mailing list posting/comment, you can at least
see how up2date that comment was and judge whether the person is
still caring about the bug.

Yeah, if we really wnat to record release info against bugs, then the
milestones looks more useful, but....
Generating a list of bugs in the release is only useful if that list
is reasonably complete. That means we need someone who really cares
about this because most people will never bother to set a milestone
and so some janitor will have to cleanup for each release. I'm loathe
to define a system that creates busy-work for someone unless they
definitely want that work.
IOW, in abence of a janitor volunteering, I'd just keep life simple
and let bugs be marked closed as they get merged via the commit message.
We can query bugs linked to commits in this way, and I feel we'll have
more luck getting maintainers to reliably add bug links in commits
than playing with milestones.

Personally I'd drop this one too

I wonder if instead of that we could just have some prioritization
tags eg
- "Regression" - something that previously worked and we broke
- "Release blocker" - we decided we must have this fixed in the
next relaase - currently we paste such bugs into the planning
page wiki for a release
- "Important" - something that's high priority to address
This confer more useful meaning that a "Confirmed" tag I think.
Anything else without those tags can be considered a "normal" bug
that may or may not be dealt.
So I wonder if it just suffices to have standalone "workflow:triaged" and
"workflow:needinfo" flags, possibly as prefixed labels, not scoped labels.
