I think the split is a good idea.  I can see there being a number of sections in Implementation Guidance beyond "good" vs "bad" test vectors.  E.g.  Which next hop is selected to forward a status report if the ReportTo EID is not in the routing table?   The time taken to write the guidance will probably exceed a first set of test vectors.

I would love some binary test bundles, as I'm currently interop testing against other available implementations and picking the lowest common denominator of functionality.  Jon Postel would be proud, but it's not ideal.
