If the new system settings value for AIRPLANE_MODE_TOGGLEABLE_RADIOS contains RADIO_WIFI, then the user will be allowed to enable Wifi while in airplane mode. Turning on airplane mode will still disable Wifi, but the user will be free to reenable it in the Settings app. We also allow access to the VPN settings under the same circumstances.
