My comment above was in response to the suggestion that ARIN "should
make strong efforts to communicate and preserve the notion that
[RFC5969] is a transitional and therefore temporary solution".
Certainly, if ARIN should "communicate" that RFC 5969 is bad, it should
do the same for RFC 3056 and 3068.

That's not what observable data suggests. Broken 6to4 has a measurable
impact on a broken IPv6 connectivity, and one of the reasons some
content providers are very hesitant to offer AAAAs 6to4 hosts. That's
not the case with 6rd. The technology is similar, but how it is deployed
and operated is very different.
