Missed the discussion process due to the different of time zones. I agree the conclusion that got by the discussion. For us, there is no much we could do in protocol design aspect. But, clearly pointing out the sedhcpv6 packets are large would be very helpful for implementers and deployment. We will add some text among with other comments we received during WGLC.
