When everything is said and done, if the root cause points beyond a doubt to crew action or lack thereof, the approach taken will be, "if it ain't broken, don't fix it". The most recent AIT from Airbus already points in that direction. Given the complexity of systems involved, on the whole, it may the wiser approach. Improvements will come when they are ready. Until then just fly the airplane.
Not saying its good or bad, just the way it is.
