It's the mother of SPOFs. (when your anti-spof solution has an spof...)

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)...
