Carefree FCS

Just seen the video from Tarnished on the military aircrew forum of the Rafale having a close encounter with the wet stuff - follows on from Typhoon having a close encounter with the concrete at Fairford. Assuming that both aircraft are probably g limited at the bottom of a loop is it a good idea to have a carefree aircraft that automatically limits g when in this scenario an overstress would have been more preferable and given the pilot the option of recovering with a greater safety margin? Are the new breed of pilots just pulling to the back-stop and hoping that the aircraft will give them enough performance and not making gate heights/speeds etc? Agreed that limiting the max alpha is a good idea as the aircraft cannot technically stall and will therefore operate at CLmax but should we not allow the pilot to decide an appropriate max g for all given circumstances - CFIT/mid-air/def manoeuvres?

Discuss please gents - after all Boeing still believe that avoiding CFIT shouldn't be limited by FCS whereas Airbus firmly believe that the aircraft should never be allowed to pull more than 2.5G regardless of the severity of the situation. Surely military aircraft should follow the Boeing lead?
