Correct. However, an option to use the system resolver for this instead
is a feature request we've been considering.

The reason: Whenever we find a security bug that affects recursive
operation only, someone who runs an auth-only server inevitably asks
whether their system is affected, and we always have to say, "well,
*probably* not, but recursive code *is* sometimes used in authoritative
servers in order to blah blah etc" and it might be nice to just say no.
