If your branch is not fast-forwardable and has to be rebased before merging, then you wouldn't be able to reuse the artifact from development branch anyway as your production branch is already somewhere else than your development branch was. If it is fast-forwardable, then individual commit IDs don't change at all and you only get a single, effectively empty, merge commit on top of them, so you actually can reuse the artifact just fine.
