This is a point. This means you are not allowing any CPE device which is
(A)A machine will follow RFC3484 to select source address
   regardless if this machine is a strong host model or a weak host model
(B)No routing function (for example, because there is no LAN behind)

So, 

(X)Even if a machine terminates PPPoE, L2TP or whatever uplink by itself 
   with no other machines in the customer premises, this machine must have BOTH models.

Then, it seems to me that this is overkill.

For example, if we create sensor networks, do we still need routing function
on all the sensor devices ? I do not think so.

Also how about if a customer has only one PC (this is quite linkly situation) ?

At the same time, please note that we have no way to identify a CPE is a router
or just a host.

So, I strongly against this text "One CPE MUST support BOTH models".

Of course, "The Service MUST support BOTH models" will be fine.
