And when you talk about "DNS operator" it might not only be one role either. Within the "DNS operator" role you have name server operators, zone editor and zone signer. All of which can be different entities, and "name server operators" can be more than one - and depending on the type of organization, zone editor and zone signer can also be multiple entities (look at the root signing stuff).

For the 70 of so domains that I host on my primary server I am the primary DNS server, editor and signer for about half of them. Secondaries are external parties in about 50% of those cases. I don't think this is very uncommon.

Yes. And even the term "DNS operator" is not very clear.
