Re: [dnssd] Draft: A DNS Query including A Main Question with Accompanying Questions

I remember this was presented back at IETF96/IETF97 in DNSOP (had to
refresh my memory).

The feedback at the time was it was hard to implement and to use; lacked
any security considerations; and involved changing resolver behavior.
The last one is the most important - it's one thing to add to RR Types that
require no extra processing; EDNS options are a bit work, but changing
resolver behavior has a very long tail in the DNS world.

(We keep the DNSOP materials back to IETF96 in github
https://github.com/ietf-wg-dnsop/wg-materials for those interested.)

I'd like to see implementations or attempted implementations myself.
