I have and remain unconvinced and or confused The proposal allows
an operator to verify a valid origin AS for a given prefix (i.e. "config"
sorry if I'm being loose with the word) by using the DNS system with
"bgp.in-addr" extensions. I'm not sure which part of the random
route announcement problem that dnssec solves in this case? It can
help with the "are they indeed are who they say they are", but it
doesn't solve the "are they supposed to be doing what they said that
they're doing" case.
And you didn't address my paranoia about not trusting the DNS
