I would like an option on export space to save only the last version of all documents and attachments. I would expect the restore operation to restore all the pages and attachments as version 1. This would be very helpful for populating a secondary site with a clean copy of data. For instance, I might need to remove confidential data before exporting or there may be preliminary data that I don't want users to see in the history. It also make the exported zip file smaller especially when large attachments are involved. I know there are some SQL based work arounds that can help clean up a space after the fact. These are difficult and error prone.
