If that is the authors' goal, then what the draft should say is that the
IID length is 64 unless otherwise specified by an IPv6-over-foo layer.

That is not what the draft says today.

I also suspect it's not the authors' goal. At least Randy and Job have
clearly stated that what they want to do is run non-/64 prefixes on today's
links (Ethernet, maybe wifi), not on some future link layer.
