Users don't care about IP at all. They just want to make sure that their apps keep working. If you switch them to IPv6, and they have faster access for IPv6 enables sites and apps (40% faster time to complete HTTP get), and they don't notice that the WAN is IPv6-only, because inside the LANs they still have dual-stack, problem solved.

There is no reason do do that in the current Internet. IPv6 is still optional. The number of users who care about IPv6 access is very close to 0 and dropping. And as demonstrated in this thread: Even the few who still do care are not willing to pay extra, or sacrifice anything, for IPv6. They will run off to your competitor as soon as they discover the price is lower there. Which it will be since they saved a lot by building and running an IPv4 only access network.
