That doesn't seem like a proper outcome — dismissing user’s data
shouldn’t be something we encourage in general. Imagine that the user
has been spending a lot of time to get the perfect picture, only to get
it randomly trashed by the original invokator.

I think once the external app is up and running, canceling a pending
operation should have no direct effect on the external app. It might be
OK to cancel the invokation of the callbacks.
