That is implicit, although I suppose I should add an explanation to that

I think you're confusing domains and TLD's here. However, your suggestion
fails to scale beyond say... two domains, because it requires host record
registrations for every name server in every domain I administer. That's
incredibly difficult to manage when you're dealing with hundreds,
thousands, or in my case, hundreds of thousands of domains.

That's brokeness completely unrelated to how the zone files are managed.
