Android's configuration changes make it very difficult to craft an API that can catch all output values and also avoid double-processing of them, and each such API we've come up with is very confusing. The cognitive cost outweighs the benefit of allowing the Activity or Fragment to consume a stream of outputs — if that's even a benefit! So far we have no use cases for a stream v. a single result code that can't be better handled inside the root workflow. Note that we update the Tic Tac Toe sample to take advantage. We also (nearly) make it's back button work properly on the initial screen, but that is blocked by #466. Closes #430.
