I didn't know that ``env_prefix`` is only an alias, which means ``CONNECTION_PORT`` and ``PORT`` treated as the same. In the [documentation](https://docs.pydantic.dev/latest/concepts/pydantic_settings/#dotenv-env-support) this behavior is mentioned only at the very end....

Thank you for your helpful comments and the work on pydantic!

I thought i put all environment variables into one ``.env``. How else I am supposed to work with them?
