In my opinion there is two type of users as usually ISP services are marketed:
1. Home user - not really interested in configuration of their devices - they just want Internet (now IPv4, soon IPv4 and IPv6) connectivity: They generaly don't use more than one LAN internally. All their devices are connected either directly to ISP device or to the home-gateway purchased at the cornet. In this case the /64 with autoconfiguration is the best option. User don't have to configure anything (may be enabling IPv6 on their computers).
This would force these places to: a) use bridging to get that single /64 onto their network thus making firewalling really difficult. b) get a 'power users' abo, which would thus make people have to PAY for getting more IP addresses. ISP's are paying their transits by paying for the *BANDWIDTH* usage. So why don't ISP's have a couple of classes (to keep it simple) which are like eg: 10Gb account 50Gb account 100Gb account This would also solve the "Those stupid users are torrenting" problem, as they are PAYING for the traffic and other costs that you actually have. Don't charge for IP addresses, charge for *BANDWIDTH* usage. If I have 200 devices on the network which don't do a thing (maybe they are light bulbs or it is my fridge) I will do much less traffic than one single user who is trying to complete his nature movie collection.
2. Power users/business users - they can configure their devices, and they want measured and reported SLAs. If they want IPv6 they can articulate their needs: /64, /60, /56, or /48 with prioritisation, filtering and other business needs. In this case DHCPv6 prefix delegation seems to be the most flexible solution. Since they can configure basic things on their device. The ISP can help them and negotiate accordingly...
Scratching the 'power users' concept, as they belong in the above home user part, I agree. Greets, Jeroen
