BTW, do you know if rbldnsd provides some options to respond to ANY?  I
see that bind has a "minimal-any" option to limit the response to one
RRset (but cannot find anything to respond HINFO.)

The reason BIND doesn't implement the HINFO option of RFC 8482 is because
HINFO synthesis requires on-demand DNSSEC signing of responses, which BIND
can't do. HINFO synthesis for ANY responses exists to help implementations
where it is expensive to iterate over all the RRtypes at a name. I don't
know of any HINFO synthesizers other than Cloudflare.
