Due to the /64 bits left I don't agree, but from the discussion so far
I understand that:

- there is indeed no point in using dynamic prefixes for privacy if
they were deterministic
- random prefix assignments scary many people

But wait, aren't ULA prefixes random? If CGNs were here to stay[1],
why couldn't they provide a "network layer privacy" [2] service? If
they claim to be so good at NATPT44, NPTv6 should be a piece of cake.
