That simply isn't true. The draft doesn't abolish the concept of 'interface
identifier', which doesn't exist in IPv4. It doesn't attack SLAAC. It
doesn't attack ILNP or draft-herbert-nvo3-ila. It doesn't attack the choice
of /64 for all IPv6-over-foos to date.

It does say two things.

1. BCP198
2. n in the addressing architecture is a parameter.
