A digest-stable copy seems popular, even when not copying signed images. Using --all can still change digests. Adding an option to ensure digests are preserved.

Also adding a missing check to enable digest preservation for manifest lists where the destination is digested.

Many users have turned to skopeo as a mechanism to copy images between registries. These users often believe that while docker pull and push can result in a different image digest at the other end, skopeo will keep the digests.
However, the situation is more nuanced, and skopeo can copy to and from many transports.
It would be good if the documentation explicitly said which options were "digest stable", ie, will always maintain the same image digest.
