The fact that delete is supposed to return a Promise kind of implies to me that when the returned Promise is resolved, then the service should be finished being deleted. But that won't be the case here. this.deleteService() will have signaled the various function calls to cancel, but they won't be cancelled yet. Is that important?
It seems like it would be pretty annoying to have to implement some kind of countdown latch or something just to make sure all the functions have completed. So, what guarantees is delete supposed to make?

Looking at Firestore and Auth, it seems like delete only guarantees that the deletion process has been started. Auth delete doesn't wait for anything before returning Promise.resolve(), Firestore shuts down some services and waits for those to complete but doesn't cancel pending promises. I don't know if this is ideal, but it's consistent for now.
Made a small change to return the result of deleteService() directly because it reads clearer, but it doesn't solve anything as far as timing.
The functions service lacks an
INTERNAL.delete()method which I think is the cause of #1683. This adds a delete method which resolves a top-level promise on the service instance which should cancel any ongoing request promises.
