Yep.

I guess dhcpcd could be used on the home router, but that's not what we're
doing -- I'm using dhcpcd on the client to test the home router.  (Plenty
of good reasons to use dhcpcd for testing, by the way, thanks for your work.)

I think so.  It's certainly helpful in the multhomed host case, and there
might be strange single-homed topologies where it's useful.

(OTOH, I'm not sure how useful is the router priority business -- I can
envision some topologies where it's going to break.)
