A third workaround would be for the System Settings app to exit whenever you are connected to wi-fi and the setup is running. That would handle the case where you connected successfully. But it would still leave you marooned if you failed to connect, and it wouldn't prevent you from launching or switching to other apps before you finished the setup.
