I maintain a few open source libraries and we have recently switched to Ruff from Flake8 exclusively because of the lack of pyproject.toml support.

These are relatively speaking small codebases, and the speed improvements really don’t make a difference for us, but with trying to get our own projects in line with current standards flake8’s refusal to support it was the final nail in the coffin.

I think the point was reasonable when pyproject.toml first came about and parsing it was a bit more of a Wild West, I can certainly understand the unwillingness to try and support it then. Now with Python itself having toml support in the standard library, and every other major tool standardizing on it, not to mention TOML being the de-facto config file for Rust projects. It just seems like a bizarre hill to die on to me now.

It’s not as if the work hasn’t been done, there are forks of flake8 with pyproject.toml support, but as far I’m aware multiple PRs with support for it have been denied.
