The other thing is I think we can support is subsystem lists ({netdev,fsdevel,stable}@vger) in the SAME git repo(s) with a different head for each list. That could make subsystem lists cheaper to archive since there's a lot of overlap with the main list. Headers like the List-Id:, Sender:, etc will still differ for archival purposes and have different object_id in git; but git should be able to delta well based on the rest of the message based on age.
