Thats true. And regardless of compressed vs regular tar, I think the OCI format working with opaque archives is extremely limiting. I hope the industry will eventually redesign to use content addressable storage per file and have metadata to describe the layer/disk layout instead. That would allow per file deduplication, and we can use tar for just bulk transfer over the wire, rather than using tar for the data at rest.
