The goal of the DNSE BoF was privacy, not authentication. For
authentication, we have DNSSEC :-) For the case where the validating
resolver is far away and we need to secure the last mile against
AD-bit tampering, well... no problem statement published, no I-D and
no BoF yet.

Why before? Encryption and QNAME minimization are both great things
and should be done but they solve different privacy problems:

* surveillance by a third-party sniffing the wire (encryption)
* surveillance by the name servers' operators (QNAME minimization)
