This looks like a nice new feature. I think it's true to say that this mechanism will work better if hosts also respect RFC 8028:

   "A host SHOULD select default routers for each prefix it is
    assigned an address in.  Routers that have advertised the prefix in
    their Router Advertisement message SHOULD be preferred over routers
    that do not advertise the prefix..."

If I'm right, this needs to be mentioned in the draft.
