I could actually see this working in reverse: perhaps there's an entry that needs to be posted before it goes public. The immediate example that came to mind was a roleplaying entry or something, where comments are an integral part of the finished product and the entry needs to be posted to collect them (which wouldn't be covered by the future draft entry feature) but then should be revealed, and as long as everybody's done before the deadline, the journal owner/entry poster in community doesn't actually need to be there if it can unlock on schedule.
