Not sure if applicable to all models but was under the impression that the 737 wing TAI system can be used on the ground. Should an overheat condition exist the wing anti-ice ground thermal switch will trip, when the bleed air temp reaches 125 degrees C, to protect the structure.
Would agree that it can't be used during takeoff as the wing TAI switches will automatically move to the OFF position. This reduces engine bleed loads and conserves thrust for climb.
Are you suggesting that Boeing do not permit use of this system on the ground or that your company do not allow it ?
