Doesn't deploying a 6to4 relay in the content provider network, along
with IPv6 access to the content provider network, exactly meet this
requirement?

No. An end system who only has IPv6 addresses has no way to access IPv4-only content, regardless of whether the IPv6 address is constructed within 2002::/16.

(and it's a bit of a stretch to imagine an end-system that has IPv4 close enough for a 6to4 prefix to be constructed, but far enough away for it not also to have an IPv4 address)
