There was a gentleman a while back that posited that having only two anycast NS records was broken by design.
It's the mother of SPOFs. (when your anti-spof solution has an spof...)

Something about "eggs all in one basket". The basket being the anycast topology.
Precisely.

It's a totally valid argument to say that domain.tld holders shouldn't be asked to add 13 nameservers for "robustness" but why not max out the payload of one UDP packet in the name of general robustness for a TLD?

Granted there are plenty of ccTLDs that aren't as robust as they could be but I think com/net/org/edu are held to a higher standard and when you have the room, why not use it? UltraDNS could even list some unicast addresses from their anycast nodes without having to change anything (or much of anything, not knowing their infrastructure/backend)...
