Personally I would dismiss the last one in favor of having versioned tags.
I have very bad experience with labels in other version control systems being
changed under my hands without any chance for me to notice it.

Basically I think the tag list could live in a VersionedFile. It would not
have any special revision descriptions or anything, just the data and
authors. So there would be no committing of tags, but you could be able to
list who created the tag, when and if anyone moved it, who and when.

Another nice to have feature would be to have "certificates" for tags, ie.
the tag would be a block of textual data, which could optionally be signed.
I think git has this.
