I have been playing around with crane pull OCI format. upon inspection of the OCI contents of the image, I realized that crane does not make image config/manifest OCI compliant. mediaType is still application/vnd.docker.distribution.manifest.v2+json/ application/vnd.docker.container.image.v1+json

On the other hand, tools such as skopeo handle the conversion automatically and give you OCI with the original manifest stripped down that conforms to OCI spec.

Perhaps this is the intended behavior, though I want to better understand why would one want to have docker manifests laid out as OCI layout.

If this is not the intended behavior, is there intent to handle this conversion? perhaps I could help.
