We left this RFC out, because jumbograms should not be used by cellular
hosts. Maybe we should have added a section on this RFC and state there
that it should not be used by cellular hosts for the following reasons:
-typical cellular link MTUs are much smaller than 64k
-packets larger than 64k take too long to send on the relatively slow
cellular links (e.g. 64k packet on 144 kpbs link takes 3.6 seconds to
send)

This is discussed in section 2.16. Do you miss anything there?

What did you expect to see about QoS? Is there anything IPv6 specific
here?

We state that MLD is a 'SHOULD' in case the cellular host supports
multicast functionality. In that case some mechanism is needed to inform
the upstream router about which multicast groups the cellular host is
listening to. This mechanism would preferably be MLD, that's
why: 'SHOULD'.
We could add a clause that the Router Alert Option MUST be supported in
case MLD is supported. The Router Alert Option is also used by RSVP.
