Machine generated PTR records are a non-starter for IPv6 in any case.

This is my worry too. Even if there is a protocol which ensures that delegations only take place to working name servers - what do you do when the customer goes off net, or acquires a new dynamic address? Does the protocol take care to *remove* the old delegation then? In general I would be worried about a (probably) much higher error rate for such delegations.
