Hi Miya, I don't find your answers acceptable I'm afraid, but aren't willing to spend any more of my time addressing them. Even though I disagree with /127s in principle, my secondary goal of trying to ensure this standards-track ID, if published, wasn't ambiguous, vague and conflicting with other standards track IPv6 RFCs also seems to be a lost cause.
