Are you moving that dev image through the lower environments, or the prod one?

If it's the prod one, I think your pattern is fine. If it's the dev one I would feel like you're opening yourself up to potential issues by confirming things on a different binary than you are publishing to the real world

What do you actually do with that dev image?

The dev image is just used to test on a CI server, if everything passes the production image is sent to our registry.
