Handing out an IPv6 /56 to a DSL or cable customer should be handled much the same way as giving them an IPv4 /29 is today -- ask, and it shall be provided, but it's wasteful[1] to do so by default.

You can't be wasteful with something that you know is already extremely plentyful.
We currently have 72 million billion /56:es. If we do /56:es of the current /16 being handed out and then change our mind, we can still hand out 1100 billion /56:es before we can discover this was wasteful and then we will have spent one 65536th of the address space available.
Give people a /56 and if they only use one NOW, you still won't have to handle administration of the customer when they change their mind. Current NAT boxes solve the problem of people only getting a single IP address. People adapt to the conditions we give them. When IPv6 is readily available there will be products that use several subnets in the home, if we start to just give them a single /64 there won't be a market to solve it this way, and people will continue to use a single /64. You can say you were right, there was no need, but you killed the multisubnet solution before it was even born.
