Nice, but why do you absolutely require Teredo even for boxes with
native IPv6? Of course there's the advantage of direct client2client
communication (less latency for clients and less traffic on Teredo
relays), but the box should at least fall back to native IPv6 if Teredo
is not available (quite odd to talk about native IPv6 being a fallback
to Teredo, but anyway).

There's at least one CPE manufacturer (quite prevalent in Europe or at
least in Germany) that filters out Teredo if native IPv6 is available by
default. They added an option to disable this filter, but that's not a
good thing. See

In the current state, the XBox One is doing more harm to IPv6 than good.
People encounter problems after having IPv6 activated (there are forum
posts which told people to disable IPv6 to fix this issue) and Network
operators will see less increase in IPv6 traffic (which lowers the
incentive to improve IPv6 support).
