### Check existing issues - [x] I've verified that this request isn't described by any existing issues. ### Request This is a request for further investigation, related to the fact that the .rock metadata file seems to be packed into the rock as a separate layer. This must have been a conscious decision? (especially assuming that all parts are squashed). But why? atm, I don't see much value in having it that way, since that layer is always going to be very specific to each rock and thus not that reusable. It would be good to revisit this decision and potentially consider squashing it with the rest of the other parts, if it makes sense. ### The problem it solves Makes the layer creation more consistent with the rest of the parts and removes the additional tiny layer from the OCI config.
