All FBW Airbuses are certified to land Flap 3 and Full. The way you handle your aircraft is your responsibility. You can't ask for someone else to cover the way you fly your aircraft. You can tail strike any of those aircrafts with poor handling.
If you intend to fly them well, the least you can do, is to follow A.I. SOPS. Changing Airbus Industrie SOPS is trying to invent the "wheel" again...
