Can you suggest that over in the GitHub issues? I will do it if it's simple to do in Hugo. A long time ago I set the summary as default in Drupal, and since there's no ads on the site or anything like that, the main reason to not do it is bandwidth, maybe, depending on how much traffic that URL gets (I was seeing like 5-10 requests per second for that URL earlier today, much more than I'd expect!).
