Interop scenarios document issues

While the specifications are extensible and there are a lot of various scenarios, it would be more beneficial to have scenarios that are useful. I find scenario #2 not very useful as I'm not seeing the completion of the scenario, the token returned (a SAML bearer token) never gets used. Not finding a real use for this scenario.
