While I agree with the goal of the draft, to keep root server queries on
the local host, I don't like how it is suggesting to run a DNS server on
localhost:53, because that is going to cause problems with running
validating resolvers on the stub. There is already enough racy
conditions on systems with virtual machines and running dhcp/dns servers
for those that are racing to own 127.0.0.1:53

But again, having a well integrated method for slaving the root zone on
a local validating stub resolver is something that everyone should do
(along with query minimalization)
