Maybe it would be beneficial for the FD bars to automatically be removed during a stall or upset, thus forcing the pilot to properly interpret the instruments. It's not as if the FD is providing any useful information.
It also saddens me that Airbus doesn't install an AoA indication on the PFD as standard. In 2015, with all new airplanes rolling out with glass displays, the six pack should be expanded to 7.
Good point on monitoring the ils with the FD off. It's probably easier to catch a problem without the FD there as a distraction.
