In practice though, I think it would probably make more sense in darcs just
to make a (auto-) clone repository for your "moving tag"...  That is just
create a "latest-clean" repository and keep that up-to-date (just as you
might have a "stable", or "buildbot-approved" repository).

Also, I think that your unrecord then re-tag situation won't work in
practice (due to other patches depending on your tag) without modifications
to darcs.
