Just after that incident my company introduced a new procedure in gusty conditions with >10kts above the mean windspeed, or moderate/severve turbulence on short finals.
In these cases we MUST land with CONFIG 3 with minimum Vapp of Vls + 10Kt. If 'Sink Rate' below 200' immediate go-around.
This is a procedure to avoid the pitch down affect during the last phase of the approach due gusts causing Alpha protection to kick in close to the runway.
The problem is we are now restricted operating into shorter runways.
I fly the airbus, and ask myslef why design the a/c like this ? Why not have a FBW system which gives proportional movements of the control surfaces, like the 777 ?
Also normal moving throttles that you could 'nudge forward' in gusts would be a great help ....
I dont make the rules, just play the game !
