You left out that SAP/SDR will not support SSM. There has been a big argument about this in the SSM IETF WG. The consensus is that source info will be communicated out of band (i.e., web pages). As usual, I take the minority viewpoint. I think that SSM will NEED something like SAP. Just think about doing a beacon project where beacons can join at will - how would you know in SSM ? I think that there sorts of consideration will lead to a re-inventing of the SAP wheel in some scalable fashion.
IPmc requires many debugging tools, builtin to the native router, to make it all work. Without sap/sdr capabilities, SSM will never take off. Having all the web pages out there are nice extras, but do not replace the needed builtin tools.
