IMHO it is too early to state that the ship has sailed for RFC6204bis already.

Is this a real deployment scenario you are designing or already having where you intend to use pd-exclude? My question regarding this specific example is why you would use RAs & SLAAC to configure 40K CE routers' WAN links attached to a single link (with one prefix) and then try to apply pd-exclude in the first place?
