That is not true, the rfc is just assuming a "real router", you can
configure the router to route traffic arbitrarily(back into the source
subnet for example).  The way it would work is as follows:

1: box A sends packet B to the default route/router
2: router looks up the next hop and sends it there,
    the next hop can be in the same subnet

The problem is that most cable/dsl/leaf node routers flat out suck as routers.

So the only thing you need is the default route, the router should
take care of the rest.
