I actually find this a huge problem. Not all distros are built around LSB, XDG, or FreeDesktop.org nor should they be since not everyone is running Linux as a workstation/PC replacement. While yes for the most part podman can be ran on the likes of Gentoo, Alpine, Arch and etc. It becomes a pain in the arse to decouple the tooling for podman away from freedesktop.org standards. Even more a pain in the arse for clustering options (e.g. podman-remote expects freedesktop.org norms, kubernetes expects docker containerd or freedesktop.org with podman, and nomad stack is just bulky vaporware).
The really sad part of this is that podman isn’t adding much of anything new that LXC or linux namespaces outside of not needing a daemon, allowing rootless execution (again because it doesn’t need a daemon) and giving ACLs around which OCI repos could be pulled from unlike docker’s wildcard by default. It shouldn’t be hard to do linux containerization without being tied to anything other than the linux kernel.
