I have added the pytest asyncio config in the setup.cfg file, I was also taking a look at and working on #1584 and the config file for pyright is recommended to be pyproject.toml (even pytest suggests its better to use pyproject.toml instead of setup.cfg here).

So as we are going to be integrating pyright soon as well, would it be better to move these configs to pyproject.toml right now? Or is it fine to have multiple config files (even though we can merge them together)? Or even merge them in one after pyright is enforced?

I hear that setuptools (which is why we have setup.cfg) is getting end of lifed soon, which is why people don't recommend it any more. Our config file is vintage to the age when we supported python 2.7.

I haven't dug through the recommended best procedure yet but I expect we'll be migrating to pyproject.toml sometime soon. Pyright might be a good excuse to make the switch now, since I definitely don't want multiple config files.

That said, adding this to the existing config file to fix something right now sounds totally fine. I'll go ahead and merge it and I'll open a bug for replacing setup.cfg if we don't have one already.
