That has always been a pretty classic combo on cheeseboards. Probably that is why they came up with the idea to put it on pizza. My favorite pizzeria has it on the regular menu too. They make thin slices of halved pears for it, so the pear is not raw after baking.
I've had similar pizzas in the US. "Sweet pizzas", so to speak, were all the rage in the mid 2010s. More often, they were branded as flatbreads.
I've made pizza topped with a brandy peach sauce (peaches sautéed in brandy, nutmeg, butter), bourbon blueberry syrup, and taleggio. Even better is peaches, arugula, and brie.
