It is exactly this sort of 'mandate it and they will come' thinking that IPv6 has relied on since it was rammed through in 1995, over _15 years_ ago - and we can all see how well it has worked. If _running out of IPv4 space_ isn't getting ISPs, etc, to deploy native IPv6, what will? Making 6to4 historic sure isn't going to add much pressure. If 6to4 has problems, fine, write a document that says something like '6to4 won't work for a host behind a NAT box because the host won't know it's true IPv4 global-scope address - so you should also not turn 6to4 on by default' and fix/publicize the issues. But thinking that changing the standardization level is going to push ISPs toward providing native IPv6 - give me a break.
