Thanks for the explanations.

But this makes "bzr tag --delete" effectively a no-op, doesn't it?
The only situation where this would work is in a local branch that is
not tracked by anyone else, which is kinda against the raison d'etre
of a dVCS.

Is there _any_ procedure that would remove a tag for good, in a way
that will propagate to downstream branches?  Tags pointing at
non-existent revisions, for example, are serving no purpose except
tripping various commands and plugins (see, for example,
https://bugs.launchpad.net/bugs/857273).
