When we originally created csv_summary output format, we didn't have a way to properly check that summarization happened independently on separate queries, so we limited this output to single-query runs.
That issue has long since been fixed, and csv_summary can smoothly output multiple query results, except that we explicitly prohibited it from doing so.
