Operationally, the root zone actually is special. It is, after all, the starting point of the name space. As far as I can tell, there are 3 ways the root zone is special:

1. How does one obtain name servers for the root zone? How does one obtain name servers for any other zone?
2. Who controls the name servers for the root zone? Who controls the name servers for redbarn.org?
3. What happens if the root zone is unreachable? What happens if redbarn.org is unreachable?

7706 describes one method to improve resiliency, performance, and privacy of root name service, with no modification of the DNS protocol or name servers. It is, of course, possible to do the same thing with any zone, assuming you have enough memory, but few zones generate sufficient interest to do so. Not sure why you’re arguing against it. Could you explain?
