A quality DNS-over-DTLS implementation will do TLS session resumption, and refresh its session keys only for forward secrecy.

> The introduction to this draft implies that it has less latency than DNS-over-DTLS, but gives no measurements in the body of the draft. Are such comparisons available so the WG can balance this against the DNS-over-DTLS proposal? Such a comparison is important, given that what you are proposing is a new encryption protocol, as compared to using the well-established DTLS.
