The problem is if you use the recommended hooks, pulling from the tool's GitHub repo, that runs off a different venv than the rest of your project. If you leave e.g. black out of your dependencies, and only ever run it with pre-commit, there's not really an issue. I prefer to have everything managed in one place, with black as a dev dependency (I use poetry) so I never use the upstream-maintained hooks, I have to write my own.
