One aspect I've found common to criticisms of DoT and DoH is that they tend
to focus on "privacy", which I take to mean confidentiality. It's true that
these encrypted transports might not provide confidentiality, since the
information in the query can currently leak in several ways.

However, DoT and DoH do provide message integrity between the client and
the selected resolver. It's difficult to argue that this property is a bad
thing.

thanks,
Rob
