Ditto.

My 6to4 router at home works fine for me and my family.
However, the problem is that 6to4 is preferred than IPv4
and Japan does not have 6to4 relay router until very recently,
so sometimes my packets have to go back and force pacific
ocean to connect an dual-stack server in my office.

The problem of mine can be solved by switching preferences
of ipv4 and 6to4. And some people that advocate deprecating
6to4 here seem to be able to live with this trivial change.

Of course, you may say that IPv6 address, including 6to4,
should be preferred for the sake of NAT unfriendly
applications, but it is not worse than losing 6to4.
