-[PEP 453](https://legacy.python.org/dev/peps/pep-0453/#recommendations-for-downstream-distributors) makes a recommendation to downstream distributors (us) that sdist tarballs should be installed with `pip` instead of by invoking `setup.py` directly. For historical reasons we did not follow PEP 453, so some formulae still use `setup.py` installs. Nowadays, most of the formulae use `pip` as we have migrated them to this better way of installation.
