It isn't a problem if the tags are already there on the changeset. Which
I think was always the case before. Only this one time a tag was added
after we started using the revision (and that changes the checksum on
the hg archive tar ball for that revision, since then it gets the tag
name added).

It is only a problem if a revision doesn't have a tag yet, but is used
in the already as base and then a tag is later added to that
revision. That is certainly a pita. But we can work around it by only
using tagged revisions in the (or not retroactively adding a
tag to a revision once we start using it with a calculated checksum).
