I have seen over-reliance on the facade pattern devolve into endless indirection that can make the code needlessly confusing. If you are already familiar with the codebase, it doesn't seem like a big deal, but when you onboard, you'll find your new teammate combing through file after file after file just to discover, "oh, there's never any external API call or specific business logic involved, we were just reading a static json file from disk that does not change its content during a single run." Using the known baked in stdlib functions for standard behavior removes a lot of potential uncertainty from your codebase (while also making it sometimes harder to test).
