VR-HYU of the incident is MSN 447. From a past where LAF was a thing, etc., today's FCS could be significantly different even on the HW level. (for bystanders, the NEOs exist from around MSN #7000 and the newborns will soon reach unit number 12.000).
If someone said FULL is less responsive and FCTM reads that FULL provides better handling in gusts and turbulence, that's not exclusive to me - quite the contrary. In addition, after all the cases of cases from Bilbao, my bet is Airbus has the books right and software finetuned.
EDIT:
hikoushi cross-posted, same thinking. Thank you.
