Sorry I am late to this discussion, but AERO uses link-local source address for
all DHCPv6 PD messaging. It works in the public domain implementations I
have been working with.

It's actually nonsensical to use some other address.   One of the purposes of DHCP is to get addresses, so if the server assumes you already have one, how's that going to work?
