there are plenty of Python packages in Fedora currently using setuptools at

because python3-devel (transitively) depends on python3-setuptools.
We would like to kindly ask you to add explicit BuildRequires for
python3-setuptools to packages where setuptools is used. It will help us
with testing new versions of setuptools in the future or with decoupling
Python and setuptools. Today, if we want to know if a package is using
setuptools, we have to do `fedpkg prep` and use grep to search for
setuptools. Using a repoquery is much more convenient.
Several packages can successfully build either with or without setuptools
(they use try-except import and fallback to distutils from the standard
library). Such packages are especially dangerous when not BuildRequiring
setuptools -- they can produce different results depending on the presence
of setuptools: either an .egg-info metadata directory (w/setuptools) or
.egg-info text file (w/distutils). RPM has troubles when upgrading
directories to files .
According to our grep based query on Fedora Rawhide, there are 621 known
packages using setuptools without BuildRequiring it at this point:
Thank you very much for your help with this.
Fixed and rebuilt in rawhide.
