Please branch and build jansi1 in epel10. If you do not wish to maintain jansi1 in epel10, 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/jansi1/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/jansi1/adduser
