Gnus use a date from X-Gnus-Article-Number in nnfolder's when expiring
articles, it could be modified to update that date to indicate when
the article actually became eligeble for expiring.

That would even work, using access-time in nnml groups is not a good
idea -- articles might not be expired at all due to backups, glimpse,
filesystems where atime=mtime etc. OTOH and similar to nnfolder, one
could have nnml touch files when a article actually became eligeble
for expiring.

I'm not saying it's a good idea though, I've no problem with the
current behaviour.
