That would not help situations where a client has 6to4 enabled (and
a non rfc1918 address) and is behind a firewall that doesn't support or
filters proto 41. At least Teredo detects whether or not it will work
before enabling the interface.
In a perfect world people would fix the routing or filtering issue. In
reality if it only affects a few sites the typical end user won't think
it's their problem.
