I don't think there is anything that special about portable computers that that can make phone calls ("mobile multihomed hosts"*). It seems to me the only thing special here is that one of the links the MMHH has is a 3G/4G etc. one, and the operators of those networks have certain views on how those networks should operate. That would seem to me to give them the ability to select what parameters are chosen for IPv6 operation over their networks e.g., stateful DHCPv6 only, prefix lifetimes of 2/1 hours etc., but to extend that to listing IPv6 protocol implementation requirements across the whole MMHH seems excessive and unnecessary. Surely the existing IPv6 node requirements RFC is enough for that?
