the endgame for provider-in-the-middle attacks is enduser validators, which
is unfortunate since this use case is not well supported by current DNSSEC
and so there's some more protocol work in our future ("noooooooooooo!!").

i also expect to see DNS carried via HTTPS, which providers tend to leave
alone since they don't want to hear from the lawyers at 1-800-flowers.com.
(so, get ready for https://ns.vix.com/dns/query/www.vix.com/in/a&rd=1&ad=1).
