I'm all for someone taking ownership of this long-neglected component -- thank you for doing so!

Maybe a way to think about this is that the canonical url is based on
the message-id, but then there's some way to distill even this down
to a tinyurl or simple integer that would be stable in the face of
full archive regenerations.
The resistance to basing this on message-id has always been that there's no guarantee of uniqueness... ...but I believe each list has some sort of counter for how many messages it's seen, so we could add another header with that number, and use as a unique id the two concatenated together... (That way the archiver can know from the content of the header exactly how to generate the same unique id as mailman, which would allow for the url-in-the-footer to happen w/o first hitting the archiver.)
Just throwing out ideas, -Dale
