Its fair to say that CPE Routers in general will not behave like routers
on their upstream link to the IP_Edge BNG node.

I would split this into two segments, a) The home CPE type Router and
b)Retail/Enterprise Router that is connected to two or more IP_Edge/BND
nodes. In case b) the use of some dynamic routing protocol would be
preferable and makes sense.

James talking about.  I and more folks thought one home to another home
communications were being discussed but actually what James was looking
at was a single home and this home's networking.  We also had a
disconnect with James because it wasn't told to us that there was a hub
sitting behind the broadband modem and then a CPE Rtr is behind the hub.
We assumed the CPE Rtr was directly connected to the broadband modem.
Now that all things are clarified and we know it's one single home being
discussed, we will look into common scenarios that Service Providers
have in mind and take it from there.

Yes, but if we conclude that it's desirable in general for CPE routers
to behave like routers on their upstream link, AND if some ISPs don't
want that, it should be a configuration issue to switch such behaviour
on or off. IMHO.
