According to this: http://blogs.cisco.com/sp/france-is-famous-for-fine-wine-cheese-and-now- ipv6/ and some more recent direct talks in French, about half of worldwide IPv6 traffic is French. The bulk of it comes from a single ISP (Free, AS12322) and their IPv6 is 6RD (RFC5569, RFC5969), a variant of 6to4. Given the constant references in 6RD to 6to4, I will point out that making 6to4 historic somehow reduces the likeliness of another extremely successful ISP implementation based on it. Although Google (in http://www.pam2010.ethz.ch/papers/full-length/15.pdf) and other measurements classify AS12322's traffic as native, it is 6RD behind the scenes. If the argument is that IPv6 "native" should be the preferred solution over "tunneled", it does not hold water. If you were to remove 6to4 and 6RD from the picture, that would set us back 10 years ago in terms of IPv6 adoption.
