You can now optimize this discussion without having to bother the whole IETF list. Just look up the counter arguments in the previously posted summary.

E.g. the response to your argument in this email:
1.a.i) Out of scope: Argue the point of header insertion or alternatives in the context of those proposals, not in the context of the core IPv6 specification. Do not try to make a preemptive strike in the core specification.

Only partly tongue in cheek.
