I don't see the need either but there was momentum to specifically suppress the wording, no need to swim against the tide.

There is no such thing as an IPv6 DFZ, please have a look at: http://arneill-py.sacramento.ca.us/ipv6mh/ietf55ilj.pdf http://arneill-py.sacramento.ca.us/ipv6mh/playbook.pdf
That suggests the "global routing prefix" shown above is the prefix a site and its immediate upstream know about but it could, at least in theory, be further aggregated between there and the default-free zone. Is that right or have I missed something obvious?
You are right but only if the address is PA. The fact that there are no PI addresses as of today does not mean there will not be a replacement for them that uses the same address semantics as a regular IPv6 unicast address. Michel.
