I do something similar because we have drafts (first drafts and drafts of existing records) in our system. My question is whether there is any downside to maintaining drafts and historic revisions in the same table opposed to maintaining it in a separate table as the OP does. Thoughts? Bloat and table optimization come to mind as potential problems, but it does make it easier to query for records.
