 The `[tool.poetry.dev-dependencies]` attribute is NOT used because of a [limitation](https://github.com/python-poetry/poetry/issues/3514) that prevents these dependencies from being pip installable. Therefore, dev dependencies are not installed when purely running `poetry install`, and the `--no-dev` flag has no meaning in this project.
