If they're using autoconfigure for IPv6 addresses, what happens if they want to share that connection? Giving them a /64 off the bat means that a very sizable fraction of your users are going to call. Phrased differently - how screwed would you be if you engineered your IPv4 network so the default was "one device only", and the customer had to call you and ask for a network config change because they wanted to hook up a $50 home wifi router? If it doesn't make sense for IPv4, why would you want to do it for IPv6?
