No worries.

No, I was simplifying those out for purposes of clarifying the first
bit. I glad that I understood the intent in that part of the state
machine.

I am as of this month, rather painfully aware of how dhcpv6-pd does
it, and all the intricacies required.

As one of many examples of tricky policy issues, I don't see a way how
to do ahcp-pd right without all the servers maintaining some shared
global state and/or potentially naking or adding a state like "I can
help you but perhaps someone else has better data, get back to me
later" - to an initial pd request.

Then there's ugh - security. Then the relay problem... ah, I shant go
into it further.

However I note that thinking about the pd problem with a clean slate
such as ahcp, rather than the decades of accumulated crutft that is
dhcp, is helping to clarify my thinking, and thank you for that.
