With the use of anycast DNS servers on the internet, TCP is no

Erm, bollocks.

Just because a few nameservers are anycasted doesn't mean that the
vast majority of non-anycasted servers may not use TCP.

Optimising the common case of simple lookups so they fit in a UDP
request makes good sense, but an overzealous determination to stamp
out TCP DNS is not helpful, since it is rather useful under certain
circumstances.

*cough* worldnic dns servers *cough*

it's part of the rfc, make sure it works please.
