And what does the resolver with a trust anchor do with the DO=0
answer?  Requery immediately because it assumes there's an attack?

If you want to punish those non-compliant resolvers, you must not
answer at all, hoping that the resolver timeout will calm things down.

Obviously, you should play such tricks only on a separate set of root
server addresses/names.
