I have recently raised an issue here on Meta about suspension for commenting. As comments were deleted and I could not register all of them, some users may ask themselves if in those missing comments there may be hidden some fault of any involved part.
Since only moderators can retrieve deleted comments, in these scenarios, where the main point of the issue is about commenting, couldn't moderators provide the whole commentary log for reference in the Meta question? Otherwise, people have to make a half-judgement based on what they can't see and making a proper account of the facts is very difficult if not impossible.
