Adding a dedicated API for test automation, for modifying device network settings such as Data, WiFi, Bluetooth and NFC.
This is an excellent idea. The one drawback that I can see from the the planned enhancement to prevent standard users from accessing the "settings" on mobile devices is that they won't be able to switch from one Wifi network to the other. (Where I work we have two networks, one for internal facing applications and one for external-facing applications).
Being able to switch between networks via API control would be useful. Having the ability to do this through the UI for manual testers would also be useful.
