Not at all. I'm suggesting (see the algorithm in
<https://tools.ietf.org/html/draft-bortzmeyer-dprive-step-2-04#section-3.2>
to switch to opportunistic mode (encrypt but do not try to
authenticate) when retrieving the DANE material. As soon as you get
enough information to authenticate, you go back to strict mode.

This is similar to what is suggested in
<https://tools.ietf.org/html/draft-ietf-dprive-dtls-and-tls-profiles-07#section-8.2.1>
