I can't comment on Podman specifically, but Red Hat's approach to the projects that they choose to focus on in the "Red Hat ecosystem" seems to be to just do development in upstream first and then whoever is working on the distros packages it for Fedora and/or RHEL. I don't see why they should put resources into packaging in their upstream projects; it doesn't seem to me that they're hostile to other distros packaging their software.

Packaging is a distro problem, not an upstream one, though upstreams should of course work with distro maintainers to make packaging frictionless.
