Arguably only installing the 1-2 dependency we need for a single test doesn't sound like a bad idea either.
And might be doable for other tests as well.

Ah, it would be good to keep the stubtest stdlib ones as they are. Because stubtest does runtime inspection, the --no-site-packages flag doesn't provide the same level of isolation as it does for when we're just running mypy; and unlike stubtest third-party, this script doesn't create venvs on the fly. It's useful to be 100% sure that it's running in as isolated an environment as possible.
Looks like we don't need the tomli requirement in daily.yml though!

But keep -r requirements-tests.txt for third party right?
I meant daily, and that's also stubtest-stdlib

Yup, the third-party one depends on utils.py, and we can be sure it's testing packages in isolation because of the way it creates venvs on the fly 👍
