This is roughly what we need: a place to represent long-term state for
the subset of issues that cannot be resolved immediately. Historically
that was very few, but what happens is that they start to accumulate
over time -- this is rather inherent in their nature.
Representing immediately fixable bugs would be fine too, but less
important.

No, I don't think so. The problem is not that the list is overloaded
for multiple uses. The problem is that there's limited capability to
search for and reply into existing historical threads unless you're a
list member with your copy of the archive, and there's no way to link
new requests with old ones like "duplicate of..." relationship in a
bug tracker, nor any easy way to filter on "still open" vs "resolved",
etc.

Yes. Having this automated would be really nice. Even better if it
could be done not just for the official upstream repo but for proposed
patches/patchsets or third-party git branches (on some sort of
request).
I'd really love if the CI were optimized to do incremental builds and
reuse artifacts as much as possible for rapid results, but doing that
right probably requires fixing missing dependency tracking in the
build.

A manually curated TODO list/wishlist on the wiki was how this was
managed for the last N years, and it wasn't really good because it
failed to link community discussion of the issue and didn't capture
things not already valued by me or community. Even with a bug tracker
it would be perfectly fine (and much more effective than it is now) to
have a TODO/roadmap, since it could *link to* the relevant tracker
items for more detail and record of what exactly is wanted or proposed
and why.
