I think the idea would be that you could re-compact with a different focus. When you compact, you can give Claude instructions on what is important to retain and what can be discarded. If you later discover that actually you wanted something you discarded during a previous compaction, this could allow you to recover it.

Also, it can be useful to compact before it is strictly necessary to compact (before you are at max context length). So there could be a case where you decide you need to "undo" one of these types of early compactions for some reason.
