The distinction is important because I do not want the presence of IPv4ll to 
break DHCP.   There have been several suggestions about minimizing the damage 
that is caused by linking IPv4ll and DHCP.   The way I've proposed eliminates 
the damage, as far as I can tell.

I agree completely.   However, in order for there to be no coupling, we have 
to say that IPv4ll and DHCP addresses should simply coexist at all times.   
We fought that battle and "lost."   Personally, I'd be happier just to give 
up on IPv4ll entirely and use the Rendezvous standard instead, because of 
this damage.   But given that the damage has been done, if the IPv4ll 
standard is going to go forward, it's imperative that we prevent it from 
making DHCP unreliable.
