Insecure DNS deployments are probably in the top five attack vectors
for remotely compromising internal network topologies, even those
sporting split DNS configurations. As you were "...deeply involved in the
IETF's DNSEXT working group" then I presume you know this.
For example, DNS cache poisoning attacks, local ARP cache spoofing
attacks to redirect DNS queries and responses, redirection of operating
system update and patching services that map to fully qualified domain
names such as "windowsupdate.microsoft.com", etc.
Correct me if I am wrong, but in my humble opinion the original intent
of the DNSSEC framework was to provide for cryptographic authenticity
of the Domain Name Service, not for confidentiality (although that
would have been a bonus).

There are many different camps within the DoD.
