Proper use case for Android UserManager.isUserAGoat()

In the Android 4.2 API there's the UserManager class and the method:

public boolean isUserAGoat ()

From their source, it looks like the method returns false all the time:

/**
 * Used to determine whether the user making this call is subject to
 * teleportations.
 * @return whether the user making this call is a goat 
 */
public boolean isUserAGoat() {
    return false;
}

It looks like the method has no real use for us as developers. Someone has previously stated that it might be an Easter egg.
