This should be in the homenet-arch, I think. It sounds so obvious to me, that I described this in a short text in BRDP: A Router should request a prefix for attached subnetworks, with DHCP-PD [RFC3633], where there is at that moment no on-link prefix for a selected Border Router.
I could make the should a MUST.
