I ment: We better not try to converge to a single routing protocol for Homenet, small office/home office networks, branch office networks, ad hoc networks and enterprise / campus networks. If distributed info semantics for prefix distribution are well defined, it doesn't matter how it is delivered. Single encoding method helps, it is not absolutely required. If a box faces two routing domains, it redistributes. With DV style of flooding, this is simple and straightforward. I still believe hosts shall be informed of information on border routers / exit links and corresponding prefix information. And I prefer hosts shall not have a need to snoop routing packets for that. Using a NDP extension is a no-brainer for me. So yes, Homenet shall select a single routing protocol for higher data rate links (next to LLN routing, that one is separate). We can check how to run a prefix distribution protocol on top of routing, or use another carrier (e.g. NDP). My opinion: put the prefix distribution protocol on top of NDP, so all nodes are informed.
