And for those cases I would agree with you and the experts. However it would have been possible to use 240/4 between CPE and a 6rd BR and CGN with CPE signaling that it can use 240/4 address it is assigned one. This could be done incrementally and would have been better than the /10 that was eventually allocated for that purpose.
