What I proposed does this; let's see:
Let's be clear: Ole did not say anything about whether your proposal does or does not meet the requirements in draft-ietf-ipv6-prefix-delegation-requirement-04.txt. Ole stated that RFC3633 meets those requirements, which it does without requiring that a PD delegating router "re-implement everything that DHCP could provide".

I want to simplify the protocol, for the protocol to be simple and easy to understand, and trivial to implement. DHCPv6 PD spec is about 20 pages long; that is one primer: the whole protocol should be no longer than that.
Of course, all of this is a moot point if the consensus is that full DHCPv6 must be implemented by every box (especially if it could be used as a router); but I don't think such exists.
For clarity, no one has stated (or even suggested) that "DHCPv6 must be implemented by every box". If a vendor wants to make PD available in a product, the vendor implements DHCPv6 PD. If a vendor doesn't think PD will be a selling point in a product, the vendor is free not to implement it. Why would DHCPv6 PD be any different from any other IETF protocol?
