How is it wrong? I’m not being deflective (or at least not trying to be). If 
I’m an attacker who wants lots of emails in whois, I’d hit up .com 140 million 
or so for each domain. In my proposal, you’d query the auth server for say 
bambenekconsulting.com once and have what you need. Why would an attacker query 
a whois record twice for the same domain?

Sincerely, I’m not being deflective I just don’t see rate limiting helping you 
in the proposed model.

I meant if you run the authoritative (and secondary) NS for a domain you could. 
If you share that with a third party, obviously you are constrained by the 
rules of that third party.
