    Ralph> Why is RPL needed for address assignment?

On a number of media,  I guess that it isn't.
On the media where classic RA/ND or DHCPv6 works, you don't need it.
On those media, you might not need P2P RPL either.

On some 6LowPAN mesh under systems, we have an RA/ND that does work.

As far as I can tell, none of these are the situation contemplated by
rpl-applicability-home-building.   

(And this is why I want our applicability statements to be very very
narrow in their scope, because these are questions that need to be
answered if we are going to have interoperability between muyltiple
vendors without resorting to yet another level of vendor forums)
