Please branch and build metis in epel10 If you do not wish to maintain metis 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 tdawson); please add me through https://src.fedoraproject.org/rpms/metis/adduser
The Fedora rawhide package of metis builds on epel10 without any changes.
