When I looked at it (perhaps the developers will correct me if I'm
wrong), I concluded that it worked this way because of the way nsd
drops privilege after binding to the low-numbered port.  It seemed to
me that because it wanted to drop privs as soon as possible, it had to
adopt some strategy of handling the requests, so SERVFAIL was the
answer.  I agree it's sort of ugly, though.
