Nor is the oven: https://www.youtube.com/watch?v=ZW_Maj0g8cg
Nor are dry ingredient spreaders for anything from cheese to sliced meats regularly used at an industrial scale for frozen pizza and bruschetta already.
The fact that all the components exist but aren't in common use in delivery pizza isn't due to lack of innovation in the area, more likely it's cheaper with better throughput to have the labour of 4 pizza chefs rather than the expertise to keep an assemblage of these machines running in all the local pizza places.
For the industrial and frozen segment they make perfect sense, but on the "hot" pizza side they're probably more useful in collective bargaining than anything else.
