For many of us (especiially the ones who have ipv6 deployed already), the
problem isn't *our* strategic choices, the problem is the less-than-strategic
choices made by the network owning the other end of the connection.  If we're
ready to talk over IPv6, but the other end instead decides to try to talk to us
over a NAT444 or from a prefix that's got sketchy history, there really isn't
much we can do about it.
