Yes, but it's got problems.
1) we'd have to use new hooks. Currently hooks around commit occur after
the changeset is uploaded (race condition on signing) or before the
changeset is created.
2) It doesn't allow for consistent operation on multi-user archives.
Basically, I think this is something well worth doing in tla.
