Certifying authorities do not share your concern.
Now that's comforting.
They have certified a lot of aircraft that needed redesign. Think of the DC10.
Just why couldn't they learn? Just why would Airbus be immune to redesign if deficits appear? Just because they flew since 1988? Great argument!
Anyway, I simply flew both systems and that's where my opinion and concern originates.
But then again, what does a simple pilot know ......
And by the way, I didn't want to be entertaining. Metaphors are here to underline a point of view.
Ostrich is quite suitable for some attitudes concerning the apparent deficit in Airbus controls.
Over and out.
