When old question without accepted answer is auto bumped to front page, we see it as edited by "Community" user - all good.
However, once there is other activity in the question - new answer or edit, that auto bump indication is lost. It does not appear in any edit history and probably not even in the moderator/10K tools like deleted posts.
Is it possible to preserve some indication of the auto bump, for example as part of the question edit history?
Motivation for this request is this answer, posted today to old question - so I wonder if the user saw it in front page and thought it's new question or explicitly digged that old question somehow.
