The intermediary can be operated by another party however, with whom you
talk IPv6 over the public internet.

Not saying this is a preferred way for a content provider to host its
data, but it may be a way out for access networks who are OK with using
NAT to reach out to the IPv4 Internet, and by extension (are OK with NAT
after all) don't care much about external IPv4 clients being able to
connect to your network.  
With such an external service, there's no need for a network to have any
IPv4 at all "on-net" (or some other term).
