Hey, everyone,

Given the diagnostic value of "any" (and similarly "RRSIG" et al), I would
prefer deprecation of only the UDP version, via mechanisms that are
"dig"-friendly.

E.g. return TC=1 (and minimal response) instead, to trigger TCP retry.

It throws out the bath water, but keeps the baby.

I am guessing here, but would this be easy enough to implement?

Brian
