New comment by ahesford on void-packages repository https://github.com/void-linux/void-packages/pull/28843#issuecomment-799360276 Comment: I wonder if this is still relevant to you. The `pep517.build` module you reference is deprecated: https://github.com/pypa/pep517/pull/83 and the author recommends the `build` module instead. Even the link you referenced for setuptools suggests using the `build` module now: https://setuptools.readthedocs.io/en/latest/userguide/quickstart.html#id5 It is this kind of constant churn that gives me pause about the whole pep517 mechanism. The Python people can't figure out what they want to do, they just know it's Betterâ„¢. Meanwhile, we add package maintenance burden chasing after them.
