Correct me if I am wrong, but won't this logic apply to all ARI functions / events?  If you don't subscribe you application to /events fast enough, there is a chance of missing this events.

Personally, I'd rather subscribe to the events before I invoked the function, versus passing the stasis application in the function.  However, on the flip side, if this is the case then I believe all functions need to expose this parameter for consistency.
