Единственное отличие заключается в том, что `HTTPException` от **FastAPI** позволяет добавлять заголовки, которые будут включены в ответ.

Он необходим/используется внутри системы для OAuth 2.0 и некоторых утилит безопасности.

Таким образом, вы можете продолжать вызывать `HTTPException` от **FastAPI** как обычно в своем коде.
