DISCUSS:

So I'm 100% in favor of the goal if this draft however:

  Their aim is to reduce confusion
   while retaining the useful aspects of the "u" and "g" bits in IIDs.

If they're now opaque then their useful attributes is that they are two
bits. the only way to know with any degree of certainty if an ip address
is derived from a mac address if if you have an L2 adjacency with the
device or have insight into how it was provisioned.

The text does not really mollify me with respect to retaining "useful"
aspects of the u and g bits.
