Broadly yes as that would be a conventional IPv6 router WAN behaviour.

Trouble from that perspective with smartphones is how that fits with 3GPPs
worldview.

Yes, it is described in RFC 7084.

I think a variation of DHCPv6 between the downstream and upstream
interfaces would be better because a DHCPv6 relay is DHCPv6 option
transparent.

The combination of a client and a server limits the options that can be
passed between the upstream and downstream interfaces. To support passing
new options, they would have to be upgraded; a DHCPv6 relay wouldn't.
