aiohttp / sniffio is unhappy with "--opt"

[MrHamel]

When I use granian with --opt, aiohttp's use of sniffio gets unhappy when trying to detect the async library, without --opt it works just fine. How I trigger this is by going to /docs in my FastAPI project, which produces an HTTP 500 - Internal Server Error with the below traceback.

• Linux amd64
• Python 3.13 with the project managed by uv + pyenv

Yeah, this falls into the same category of #387 and #323.
There's no plan to fix this: in fact I'm planning to just remove the --opt option at all given the actual performance gain in latest Python versions is somewhat unclear.

Gonna keep this opened until the option is removed.
