Most things are storing more than just container images in OCI registries. This stores images plus metadata like kubernetes manifests, configuration, etc. all in the registry (I assume, I only skimmed the docs). People do this because the registry is the source of truth for what their production can talk to, for example if they use a managed registry or deploy their own like Harbor it simplifies access control and locking down your service.
