I think I'm okay with "resolvers SHOULD send DO when priming."  Seems like BIND and Unbound already do this.

Do we also need to say that the resolver SHOULD/MUST retry with DO=0 if there is no response to the first priming query?

The more important question may be: what shall the resolver do if validation of the priming response fails? I'm skeptical that we, as a group, will be willing to say that the resolver should refuse to forward any queries to a root unless validation succeeds.
