I love pyproject.toml. I managed to get rid of setup.py, requirements.txt, requirements-dev.txt and MANIFEST.in, and I'm not far from having no setup.cfg soon.

All others stuff (CI/CD workflows, linters, formatters, code of conduct, funding, issue and PR automation, dependency bots, ...) moved to .github.

Now I have a clean and tidy Python project with a tiny 12-items root directory: https://github.com/kdeldycke/meta-package-manager
