But if you are certain that the content that you are returning is serializable with JSON, you can pass it directly to the response class and avoid the extra overhead that FastAPI would have by passing your return content through the jsonable_encoder before passing it to the response class. I know this obfuscates the usage of the router, but I think it makes larger projects easier to handle.
