Would it be a good idea to allow usage of environment variables on top of cli argument/options ?

Description

As lots of apps run in containers and environment variables are a first class citizen for configuration options, I was wondering if is wouldn't be a good idea to add into https://github.com/fastapi/fastapi-cli/blob/main/src/fastapi_cli/cli.py Environment variables alternatives to cli args. If it's already the case, I failed to find it in the --help

Like FASTAPI_HOST FASTAPI_PORT etc ?
