Comment(by each):

 Replying to [comment:3 jelte]:
 > - note: If I read this correctly, the Rcode that would in the end be set
 by this code for data that is not found changes from current behaviour
 (right now it returns REFUSED, not SERVFAIL). I prefer this new one (and
 do REFUSED because of ACL, not data presence) :)

 But REFUSED is what you get from BIND 9.

 Of course, BIND 9 *can* do recursion, and it's the allow-query-cache and
 allow-recursion ACLs that prevent it from doing so, so the REFUSED *is*
 happening because of an ACL, not data presence.  But we're aiming for
 compatibility with BIND 9 here, and auth-only name servers send REFUSED
 when you ask for a nonexistent zone.

 (REFUSED may be a better choice than SERVFAIL anyway because a resolver
 that gets SERVFAIL will keep trying other name servers in the NS RRset,
 whereas with REFUSED it could give up immediately.)
