What would you like to be added:
At https://github.com/gardenlinux/gardenlinux we use podman for GitHub workflows. Interaction between podman and python-gardenlinux-lib would improve functionality of the existing OCI handling.
Why is this needed:
podman pushes images from local to remote repositories. python-gardenlinux-lib improved OCI handling would improve this process to not overwrite exising manifests.
