The kind of painfully obvious solution, especially when we consider the effects of the much-ballyhooed "Internet of Things," is that we have to allow for prefixes > /64.
It's not just home nets. What about automobile nets, or more generically, "vehicle nets"? Are we going to try to rationalize why every vehicle on the road, sea, or sky should also be given a /48, because after all, for sure each subsystem in that vehicle will also need to be able to have its own hierarchical subnet structure? I think the time has come for even something like SLAAC to be modified, to accommodate IIDs less than 64 bits. And isn't it convenient that the original idea of creating IIDs out of MAC addresses has lost favor in recent years? Egregious waste of resources, in this case IPv6 address space, should make people uncomfortable. I think we need what amounts to CIDR, applied this time to IPv6.

It's to have a bit field wide enough to allow flexibility in the automation of the hierarchical assignments, not to create 65K subnets. I never asserted it was because we needed 65K subnets.
