Paul Vixie:

no resolver should be sending single-label names in DNS requests, period.
... if RD-bit is set. single-label queries to root-servers are the valid exception?

today I checked our data for queries to localhost. As expected they do happen but very rare. So I wouldn't expect collateral damage if our resolver answer NXDOMAIN some day.

Every stub resolver should be smart enough to avoid unneeded network traffic + latency.

I support the draft.
