Ephemeral addressing is a fact of life. Yes we can pretend that the whole 
world can use static addresses, but that is just living in a fantasy world.

Ephemeral addressing is currently deployed. For common cases software has
checks that something has changed and reacts. Of course, this fails for 
uncommon cases.

I'm improving an existing configuration protocol. From day one RAs provide
configuration information related to a link. What we find is that in a
world where devices move around, RAs needs to provide some extra information
to allow a device to figure out whether it's link has still the same config
or that something has changed.
