Mostly portability (which would be better if it was in-tree), but also
some SERVFAIL situations. For example for IPv6 reverse lookups OUTSIDE
of the NAT64 prefix (so for your native path). The code synthesizes PTRs
for the NAT64 prefix, I guess it is broken at this point. IÄm going to
report that, but the slow release cycles of ecdysis makes it annoying.

Probably. I was looking for a proof of concept. Also there might be
other situations where you need to do a DNS lookup from the module.
