2.3.0 added inline ignores. We should probably use those for single occurrences like froms.

# codespell:ignore froms

This sounds way too chatty to me. Putting all the config in one place sounds more intuitive and sensible to me.

I do wonder if we should just skip the whole mypy/test/ and mypyc/test folders entirely.

Personally I'd also just move the config to .pre-commit-config.yaml directly. Don't think any one is ever running codespell outside pre-commit.

This also allows us to use the pre-commit files filter as well with exclude_types: [pyi, test] and exclude: ^(mypyc/external/|mypy/test|mypyc/test).

Ignoring typos in all tests sounds a bit lazy. I detest those cryptic regex syntaxes and have struggled to make them work when configuring both mypy and black. I much prefer the config of pytest and ruff which do intuitive filtering without ^(|) which might be great for computers to parse but is suboptimal for those of us that do not have a masters degree in computer science.

The point of PEP621 is to concentrate the project config into a canonical file. Some users may choose to run codespell on the command line and it would be a shame if they did so without access to the config that was stored in a hidden file.
