Actually, routers doing SLAAC on their WAN interface is supported in
RFC7084, "Basic Requirements for IPv6 Customer Edge Routers" (W-1 and
WAA-1 requirements).

I think SLAAC on the PE-CE link and DHCPv6-PD for the downstream is
the most accommodating model as, as Mark said, it allows a PC to be
directly plugged into the service, which is useful even if just for
troubleshooting of the service.
