I def get it, but it just seems like a fight not worth fighting anymore, at least not in the areas I work I guess. I work in my languages' type system first and rely on things like serde when some sort of conversion is necessary. If I suddenly got told to switch from JSON to XML for some upstream API it would be annoying but still firmly in the "solved problem" territory. I guess I'm saying use whatever interchange formats you have to and maintain the primacy of your internal type definitions

I'm sure there are plenty of arenas where this doesn't make as much sense but I suspect it's common
