question: Docker Media Type versus OCI Media Type

[joaopapereira]

Is there any particular reason for us to be using the Docker Manifest media type in places like https://github.com/google/go-containerregistry/blob/main/pkg/v1/empty/image.go#L32 instead of using the MediaType defined in the OCI Image Spec?

This issue is stale because it has been open for 90 days with no
activity. It will automatically close after 30 more days of
inactivity. Keep fresh with the 'lifecycle/frozen' label.

Additionally, this causes issues with certain platforms such as OpenShift that will report unsupported media type dockerv2s2. I'm having to convert everything to OCI format but it super annoying having to do it with this too.

Perhaps as a way of keeping backwards compatability we could add a constructor that allows us to specify the media type?
