The cleanup is the same as when deleting a key, and then writing it again. The old blocks are deleted via the existing delete path. If there is a snapshot covering the key, the old blocks will be retained as usual. Overwriting a key in Ozone is effectively the same as a delete and a create in a single call. The atomic rewrite change simply blocks the change if the key was changed. Otherwise the functionality is unchanged.
