[fcgktnzb] Higher pizza oven temperature

Pizza is normally cooked in a very hot oven (900 F).  However, is that temperature optimal, or simply the practical limit of a certain form of oven technology?  Would pizza be different, better, if an economically competitive method of reaching higher temperatures were developed?  How much higher?

The first speculation is that thin crust pizzas could be cooked much quicker, perhaps a custom pizza in under a minute.  This would change the industry.
