I don't think this is going to solve the problems of poor quality chargers. Recalling the Google engineer testing large numbers of USB3.0 cables, his Chromebook was damaged because a bad cable reversed the wiring of the power and data lines. Just because your phone asks the charger for its signature doesn't mean it won't get max continuous voltage to its DATA_RETURN channel instead. This is an unnecessary complication that isn't going to solve any problems, just add new ones.
