You don't want to do this. CNAME + NXDOMAIN is the correct response for
an authoritative server without recursion when the CNAME target needs
chasing. The recursor knows that this means "oh, the authoritative
server doesn't know anything about the CNAME target, I need to find it

No. No, it really shouldn't. Why would you possibly want to do this? The
DNS RFCs are pretty explicit about this.

What exactly are you trying to achieve here? You're going to have to
explain this, because basically what you're asking for here is a
*broken* nameserver. The behavior you're claiming as wrong is exactly
what it should be.
