The sharp turn-off of the water from the valve can create a pressure wave. that's one reason why they put in a restrictor...it will change the pressure during refill slower, putting less stress on things. Odds are yours won't fail, but it is somewhat irresponsible IMHO, to ignore the manufacturer's engineering and recommendation.
