Crosswind Limitations on all the aircraft I've ever flown are advisory only, hence I don't consider them, only what I know the pilot/crew is capable of doing. The fact that somebody doesn't want to fly when it's windy is something I find comical. Going past this A330 limitation would be hard/impossible to justify since it seems like a hard limit from what I've read in this thread, but if the fix is/was changing the rate at which the engine is spooling up then the fix is contained in the pilot's hand, don't think changing software should be necessary.
