What you are asking is what won't SSP accomplish. It's difficult to answer those questions before the design work is done. So lets quick arguing about if it should be done. Get it done and see what it buys us.

Before setting out on change, establish realistic expectations. Currently your conversations should be related to that goal. What will domain-wide assertions accomplish? What threats will this address? There are a few areas where domain-wide assertions relating to use of a protocol could be beneficial, such as when detecting unauthorized servers. Beyond the immediate domain and server, things are rather murky.

Spend some effort explaining what you envision.

Provide realistic assessments of what it can accomplish with respect to current problems.

Play devil's advocate with what new risks could be created.

When you say get 'it' done. I can only guess what you mean. Hardly a basis for a charter. : )
