I wonder, for those who feel a loopback interface is important, is that 
because you want the CPE router to be pingable regardless of any PHY 
interface status?  If that's so, since the document's focus is on router 
behaviour, perhaps it is this behaviour should be explicitly mentioned.
Section 5, paragraph 1 states 'optional Loopback network interface, facing 
the Service Provider upstream, which initiates stateless DHCPv6'.  A 
loopback interface doesn't really 'face' any direction.  You might want to 
change the wording to something along the lines of 'optional Loopback 
network interface initiates a DHCPv6 request toward the upstream SP'
Also I notice in the same paragraph, "recommend the CPE Router WAN 
interface acquire its global IPv6 address using stateful DHCPv6 for 
administrative control of the router".  This makes it sound like DHCP is 
recommended for administrative control where I think you mean the global 
address is recommended for administrative control and provisioning of 
proxied services to the downstream devices.  Why not just say "recommend 
the CPE Router acquire a global IPv6 address for administrative control 
..."
