so this is an intentional design decision.
The Airbus and Boeing FBW computers design considerations for generic errors… The ELAC is produced by Thomson-CSF using Motorola 68010 processor, and the SEC is produced by SFENA/Aerospatiale using Intel 80186 processor
Airbus (or the DGAC) was not willing to accept that a fault with the same piece of code in two separate computers could cause the loss of an aircraft.
