Ya, I think that is part of the importance of separating out the effects that resulted from the command. If I want to benefit from the "state rewind" capabilities, to bring my DB back to a certain point in time, for example, I can simply play back the DB writes that occurred and perform those updates directly. Otherwise, I would have to replay the commands, ensure that my application state for processing the commands is exactly the same as it was when it last processed those particular commands, ensure that all undesirable side effects are disabled, etc.
