Also agree. 

<hs> 
Not quite.  The unnumbered model is clearly saying the WAN interface
only acquires on a link-local address.  But the WAN interface of the CPE
Router has got to have a global IPv6 address.  So what choice does the
CPE Router have but to automatically spawn a Loopback interface that
will get assigned a global IPv6 address (using SLAAC, DHCPv6, or one
address from the IA_PD when the Loopback interface uses, say, stateless
DHCPv6 to acquire an IA_PD).
