Please branch and build python-twisted in epel9. If you do not wish to maintain python-twisted in epel9, or do not think you will be able to do this in a timely manner, the EPEL Packagers SIG would be happy to be a co-maintainer of the package; please add the epel-packagers-sig group through https://src.fedoraproject.org/rpms/python-twisted/addgroup and grant it commit access, or collaborator access on epel* branches. I would also be happy to be a co-maintainer (FAS: salimma); please add me through https://src.fedoraproject.org/rpms/python-twisted/adduser
note: at some point there's a repo for this for c9s but it's been retired: https://gitlab.com/redhat/centos-stream/rpms/python-twisted/-/blob/main/dead.package.c9s
