No argument there.  AXFR from existing root servers is a non-starter.

Well, TSIG is good enough for the root operators: the root zone is
protected via TSIG as it travels from the stealth master servers
operated by VeriSign to the various root servers.

I further note that the canonical publicly available root zone on
ftp.rs.internic.net is PGP signed.

I think we can safely attribute such queries not to broken full
service resolvers but to inappropriate queries issued/leaking from
upstream applications and stub resolvers.  Having a local recursive
name server authoritative for the root would absolutely stop such
queries from reaching the roots.

Crap to the roots.  Although, as John Crain pointed out, the root
operators really need to provision for attack scenarios, and attack
traffic dwarfs the crap by orders of magnitude.  So this may be
solving a non-problem, but it doesn't hurt to discuss the idea.
