They could even have a Fedora Copr repo, where they push out the updated .spec file and get a proper package build for all Fedora, RHEL/CentOS and more distros. With proper RPM packaging and repository. Push a new build and all users gets an updated package at their next update cycle.
That's a reasonable path to get started with preparing packages to become part of the native yum/dnf repos at least. And that across a lot of distributions and releases in a single go.
