Probably yes.

Yes, I do.  In case of Git, I've got trouble with understanding how to
actually implement the "transferable" part with Git.  The Mercurial
way is easier to understand, but it means that tags may need some sort
of "tag at this revision" qualifier to disambiguate, which is rather
problematic.

Oops, thought this file was versioned.  Things like

  <http://tycoon.hpl.hp.com/changeset/932:931d181e9f58/.hgtags>

suggest it was at some point.
