Please branch and build python-configupdater in epel10. If you do not wish to maintain python-configupdater in epel10, or do not think you will be able to do this in a timely manner, I would be happy to be a co-maintainer of the package (FAS: salimma); please add me through https://src.fedoraproject.org/rpms/python-configupdater/adduser
Added you as a co-maintainer. Cheers.
