RFC7278 says:
"The LAN link RA configuration must be tightly
    coupled with the 3GPP link state.  If the 3GPP link goes down or
    changes the IPv6 prefix, that state should be reflected in the LAN
    link IPv6 configuration. "


In an arbitrary topology, i.e. with multiple routers and hosts.
Why do you do think this will work?

If the the RFC7278++ deploymenent model is one of ephemeral addressing, is the expectation that any time the cellular link flaps, the user should do the equivalent of a logical power reset of all devices? That would of course also assume those prefixes were not hard-coded in configuration files, DNS etc.

It is of course possible to provide long-lived prefixes also with this hack^H^H^H^Hmechanism. But that didn't seem like what Cameron was proposing.
