Yeah, I see this as pretty similar to the debate over type-safe vs. dynamic languages. It used to be that people argued that dynamic languages were just way easier to use, and type-safe languages were just an optimization. But I think the real issue was that the tooling enabled by type-safe languages didn't exist yet. These days, TypeScript is no faster than JavaScript but is very popular, because of the tooling it enables, like editors with auto-complete and jump-to-definition.

I think protocols still don't have the level of tooling that makes it really obvious why schemas are better.
