Hm.  I would suppose that the only way to get a dependency on a tag
would be an explicit dependency (eg via "darcs commit --ask-deps").
Using "darcs unrecord" would be a little risky since third parties
might depend on the tag, and then they'd be in pretty big trouble
(although I suppose you could handle that by having the moving tag
depend on all previous fixed tags for that attribute, in the case in
point "branch-friendly").  But it seems like it could work in
principle.

That's hideous!
