Felix's SCR implementation registers an introspection service, SCRService. The presence of that service will indicate that SCR is running, and it can be used to query the state of the declarative services, e.g. which ones are active, which are waiting for dependencies, etc.
Unfortunately, like Richard's suggestion of looking at the SCR bundle state, this approach is specific to Felix. I would love to see the SCR introspection API standardised in the spec.
