[cabfpub] BRs section 9.16.3 (exception for laws)

Putting on my "How might I look for loopholes in this language", it's
possible to conceive of an evil insider/collaborator attack (whether
malicious, state sponsored, accidental, or otherwise) with respect to the
"receiving confirmation of the receipt of the message" portion.

Perhaps this is over-thinking it, but how would you feel about "receiving
confirmation that it has been posted to the Public Mailing List and is
indexed in the Public Mail Archives available at
https://cabforum.org/pipermail/public/ , so that ..."

This accomplishes several things:
1) It ensures that such disclosures, if any, receive public attention,
rather than just the CA/Browser Forum's internal lists and membership
2) It moves from "receiving confirmation" (which can be interpreted as,
say, the next-hop SMTP server acknowledging receipt, but never forwarding
to the CA/B Forum list) into something that can be objectively quantified
over a secured medium (assuming a certificate for cabforum.org is not
3) It removes ambiguity as to who is responsible to confirm (can the member
themselves confirm, if they are a member? Does the Chair confirm? Does the
questions answerer confirm?)
4) It allows the flexibility for the member to themselves forward from the
questions@ list to the public list, reducing the latency involved and
giving greater flexibility, while still accomplishing the necessary
transparency goal

I realize this is fairly pedantic, but certainly, transparency and
robustness seem useful, and it doesn't seem significantly more onerous.
What do you think?
