Right, I understood. The other case I mean is not one that's broken, but
a helper that's designed to provide a password from a read-only store
(which presumably doesn't have _this_ password, else why would they be
providing it in the URL?).
It is not going to help that the clone will feed the password to such a
helper because it will (correctly, and by design) ignore any "store"
requests.
In other words, I am agreeing with you and indicating that there are
even more cases where a non-empty helper config will mislead us.
I'm going to try to re-work the patch to do this check-at-the-end
technique, and probably try to make the UI for clearing and seeding
passwords a bit more friendly, too.
