Это по-прежнему поддерживается благодаря **Pydantic**, так как в нём есть [встроенная поддержка `dataclasses`](https://docs.pydantic.dev/latest/concepts/dataclasses/#use-of-stdlib-dataclasses-with-basemodel).

Так что даже если в коде выше Pydantic не используется явно, FastAPI использует Pydantic, чтобы конвертировать стандартные dataclasses в собственный вариант dataclasses от Pydantic.
