By the time the domain object is deleted, there _are_ no subordinate host names underneath it, or the deletion wouldn't be permitted. You may consult the EPP specifications for all of this, by the way, since I think all the registries we're talking about use that as the protocol any more. Note that we're only talking about registries that use host objects, and not ones that use the domain attribute approach. There is no communication path between the two registrars (in EPP terms, "sponsors") in the registry such that RegistrarA can say to RegistrarB, "Hey! You're depending on this record, and I'm about to delete it." That's actually the path I proposed to create (with some timers, so that deletions could happen in time) some years ago, and I was told it was too hard and too complicated and nobody would do it and tin soldiers and GNSO and ICANN coming and we're all gonna die. I decided that fight wasn't worth having, so I didn't have it. Perhaps you think there's a worthy windmill there. > What is currently being done leaves a zone that "works" some of the > time for some servers.

Yes, I agree what is being done now is stupid. I think the overwhelming response among registries and registrars was to tell people not to set up their zones this way, and they won't have such a problem. That is also a solution to the problem, I note. "Doctor it hurts," and all that.
