That comment ("hosts should be able to opt out") sounds like an
interesting and irrelevant comment. If for example I am using NAT in
some form to implement GSE (such as using Lancaster University's
prototype Linux implementation), and am using a ULA internal to a
network, the ULA will not have routing outside and the only external
routing in the network is likely to be a default route leading to the
GSE gateway. So the effect of opting out will be to disable external
connectivity. Think about the mechanics of this...
Good thing that STUN already defines operation for detecting NAT66
mappings...
