So each host will end up with a /64?

How exactly are end-users expected to manage this?  Having a subnet for
the kitchen appliances and a subnet for the home theater, both of which
can talk to the subnet for the home computer(s), but not to each other,
will be far beyond the abilities of the average home user.
