You don't really imagine that end-users will require more than 2^8 subnets, but that they will want several levels of very simple, nibble-aligned routers within their network?
Not necessarily nibble aligned, but, multiple bits per level, yes.
This is perhaps a good discussion to have. I, for one, see CPE vendors still shipping products without IPv6 support at all, let alone any mechanism for creating an address or routing hierarchy within the home without the end-user configuring it himself. I am not aware of any automatic means to do this, or even any working group trying to produce that feature.
If we are stingy in address allocations, it will stifle such innovations as the vendors tend to develop to the lowest common denominator. If we make the allocations available, innovative ideas will make use of them.
Is it true that there is no existing work on this? If that is the case, why would we not try to steer any such future work in such a way that it can manage to do what the end-user wants without requiring a /48 in their home?
No, it is not true. I suppose that limiting enough households to too small an allocation will have that effect. I would rather we steer the internet deployment towards liberal enough allocations to avoid such disability for the future. Have we learned nothing from the way NAT shaped the (lack of) innovation in the home? Owen
