 In your previous mail you wrote:

   Good morning. Having been away from the list for a while, it's not clear
   to me what (if any) the consensus (and subsequent decision) is regarding
   inclusion of the IPv6 Flow Label field in the AH ICV. If consensus and a
   decision were reached, what were/are they?

=> a consensus was reached and its result announced by Stephen Kent
(1- keep compatibility, 2- fix the rationale).
Cf draft-ietf-ipsec-rfc2402bis-08.txt:
        (*) The flow label described in AHv1 was mutable, and in
            RFC 2460 [DH98] was potentially mutable. To retain
            compatibility with existing AH implementations, the
            flow label is not included in the ICV in AHv2.
