FWIW, I don't care for that one bit. Yeah, message IDs are pretty
opaque in many cases, but at least they're not designed and built to
be opaque.  An example of what would be lost is the ability to find
a message given one of these URLs in any other archive, such as one's
personal mail archive.  (Unless one sets up a mapping table to match
this transform, which would be a big PITA.)

If you remove the ability to find a message in the archive from its
original message ID, I will be REALLY unhappy, because that will break
lookups in the other direction (ie, given a message in my local files,
go find it --- and its thread --- in the PG archives).

On the whole I don't see any good reason to change this.
