# Following the same logic, should modern name servers strip out other new
# record types, in hopes of protecting innocent (and broken) resolvers?

no. i was mistaken, but not about that. i thought there was a way to
signal dnssec awareness that wasn't DO=1. if there were, then i'd say
any requestor who could signal dnssec awareness and also signal that
dnssec metadata wasn't wanted, shouldn't get it, even on qtype=ANY.

# As Mark points out, the general answer is "no" -- we're willing to let a
# resolver that asks for ANY get unknown RR types and, if it can't cope with
# the answer, we're willing to let it break. I don't see any need to treat
# the DNSSEC records differently.

i wasn't worried about seeing something that wasn't understood, i was
looking to optimize message size and avoid truncation/fragmentation/tcp.
