Do we improve things if we make tags version controlled?

My understanding of tags is probably incomplete but it at least
connotes creating a name for a snapshot of version information.  What
would it mean to make tags version controlled?  Would you be able to
revise the version information associated with a tag and have a
history for the version information associated with each tag?
