According to this:

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.

To quote from the draft (anyone read it?:-)

"   6rd [RFC5969] utilizes the same encapsulation and base mechanism as
   6to4, and could be viewed as a superset of 6to4 (6to4 could be
   achieved by setting the 6rd prefix to 2002::/16).  However, the
   deployment model is such that 6rd can avoid the problems described
   here.  In this sense, 6rd can be viewed as superseding 6to4 as
   described in section 4.2.4 of [RFC2026]"

6rd good; 6to4 {as described in section 4.2.4 of [RFC2026]} bad.

That's doesn't follow. 6rd borrows a mechanism used in 6to4, 6rd has no
dependance on host 6to4 implementations or the 6to4 any-cast address.

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.
