This is indeed super error prone and, as we discussed in the meetings
pre-UDS, the behavior has been changed in the Go port to become more
reliable. The relation-departed hook is *only* called when the user
kill the relation/service/unit for real. A box-down will not trigger
it anymore. That may come back in the future as a specific hook.
