Just like 'push' 'create' doesn't error on no-op and doesn't create a stash commit – so you still need to handle this edge case manually. I was thinking of using create-apply pair for this use case but push-pop has added benefit of preserving a user-accessible stash entry for manual recovery in case stash can't be cleanly applied after the operation.
