I did not know about these bots. A ‘problem’ I often see is that an issue after it is closed (or even while still open) is enormously long, filled with good discussion. Lot of that discussion is not on the mark for that issue, but still potentially relevant to the project. Also if a project is under-documented, you have many people explainging aspects of it to others. In that case you also might want the option as maintainer to mark the text and send it to a documentation queue for review and inclusion.
