The technology specifies that a "network" should be assigned a /64 but this thing called a "network" may not be an Ethernet broadcast domain. Different people will do different things with devices and this will lead them to use different address allocation strategies. For instance, consider an RS-232 cable daisychained through a factory with modems to handle the signal strength amplification when the signal gets too strong. Imagine 10 devices attached to this daisy chained RS 232 cable which use IPv6 to communicate. One might consider this a network or one might not.
Is this decision a public policy decision or not?
No, as this is not related to policy. But if the owner of that network comes and asks for addresses, the policy has a very clear answer: he will not get "10" addresses, but at least a /64. If the daisy chain is organized in a way that more than one broadcast segment makes technical sense, he will get more than a /64. (And *this* discussion is precisely about the question how much "more than a /64" is - a /56 or a /48).
