Most people will have more than one device. And there is no NAT as you
know it from IPv4 (and hopefully there never will be. I had to
troubleshoot a NAT related problem today and it wasn't fun.[1])
And I want more than one network I want to have a firewall between my
fridge and my file server.

RFC 3177 suggest a /48.
Forget about IPv4 when assigning IPv6 Networks to customers. Think big an
take a one size fits all(most) customers approach. Assign a /48 or /56 to
your customers and they will never ask you about additional IPs
again. This make Documentation relay easy. ;-)
