Right. Note that this is pretty much the same functionality as a NAT64 provides.
4) TCP MSS rewriting on edge devices and NAT box to better cope with lowered effective maximum packet size OR a way to use a higher MTU on the pathbetween the edge device and the tunnel box.
IPv6 routers could advertise a reduced MTU. On the other hand, that has the downside that end-to-end IPv6 traffic now also has to use the smaller MTU.
