Typos happen often. On old posts there's a lot of clutter in the first comments that simply point out typos in the question or answer. I assume it's fine to flag these for deletion?
This seems fine since one of the provided reasons for flagging is that this comment is no longer needed. My only concern is that this a very minor thing to throw on the queue of stuff to review of those who review such stuff. (Do only diamond-mods look at flagged comments?)
Also, is it alright to flag comments that asked for details/clarification that were eventually added to a post, since those are no longer necessary?
