Except the camera wouldn't know about all the lens.
Even DxO software cant cope with large whites (which is a major reason one might buy DxO) - so it would be a logistical nightmare trying to maintain the firmware as new lens come to market several years down the line.

That wouldn't be the case if the necessary information comes from the lens itself. If lenses are equipped with microchips that fully describe the optical characteristics, then the AF system wouldn't need firmware updates.

So a whole new system then? ....

not necessarily. Canon EF and EF-S lenses are already chipped. They just need to write a couple of additional "optical characteristics" bits onto them. For existing lenses in the field it might be done attached to a camera via FW-Update.
