* Wenn Sie FastAPI nicht verwenden und stattdessen Starlette direkt (oder ein anderes Tool wie Sanic, Flask, Responder, usw.) verwenden würden, müssten Sie die gesamte Datenvalidierung und Serialisierung selbst implementieren. Ihre finale Anwendung hätte also immer noch den gleichen Overhead, als ob sie mit FastAPI erstellt worden wäre. Und in vielen Fällen ist diese Datenvalidierung und Serialisierung der größte Teil des in Anwendungen geschriebenen Codes.

Ela é importada/incluída diretamente no FastAPI para que você possa importá-la de `fastapi` e evitar importar acidentalmente a alternativa `BackgroundTask` (sem o `s` no final) de `starlette.background`.
