I'm happily using podman only. Lightweight, secure by design, sweet integration with systemd as an orchestrator: a perfect middle ground when the complexity of k8s isn't needed.
Sadly "docker" is just a synonym for "container" for most people, so the main issue is that most projects only ship a compose file. Hopefully they'll ship quadlet files too, some day.
Alternatively, a public repository for sharing quadlets for popular open source software would be great.
