I cannot determine what the DUID will be in advance for any given client, yet I must do so in order to build a host definition that will allow me to allocate its correct address.  So unless I have a means to extract out and allocate the address based on the MAC, I am stuffed :-(

I really think that all you're doing is making a very strong argument in
favor of using stateless auto-config for addressing.  The MAC and the
prefix determine the address.
