* Se você nunca utilizou FastAPI mas utilizou diretamente o Starlette (ou outra ferramenta, como Sanic, Flask, Responder, etc) você teria que implementar toda validação de dados e serialização por conta. Então, sua aplicação final poderia ainda ter a mesma sobrecarga como se fosse desenvolvida com FastAPI. Em muitos casos, a validação de dados e serialização é o maior pedaço de código escrito em aplicações....
