Package omniverse/python-configparser (https://omniverse.artixlinux.org/x86_64/) is at version 5.3.0-2 and has the description
"backport of configparser from Python 3"
But it is a python3 package, so "backport [...] from Python 3" seems not be correct.
in the AUR there is aur/python-configparser (https://aur.archlinux.org/packages/python-configparser) at version 6.0.0-1, which coincides with upstream (https://github.com/jaraco/configparser/tags).
Regards!
Updated, and changed description to dev's on github.
