Today, we use the very informative SPMI diffs pipeline to make decisions and observe diffs before merging changes, but the summaries quickly expire, and so they are not as useful as they could be for looking at past changes. It would be great to have some (preferably automatic) way to save them (perhaps even with the .dasms).
