Only mods can see deleted comments

Why can only mods see deleted comments, but any user with sufficiently high rep can see deleted questions and answers?

I am not saying this is a bad idea. (Though if you think it is, I'd love to know why.) I am curious what the significant difference between questions/answers and comments is in this respect.

My current thoughts:

Advantage: Most deleted comments are garbage.

Disadvantage: There isn't any real way to "audit" or discuss moderator behavior, as with deleted posts. This cascades into other areas, such as the decision to lock a post because of (deleted) off-topic comments (see How many off-topic comments does this have?).

In my limited experience most deleted posts are garbage too. What is the significant difference?

    Well, comments are second-rate citizens in comparison to posts. In addition, most deleted comments are either a) offensive, b) off-topic, or c) obsolete. So do you really want to see that? – hichris123 May 23 '14 at 1:16
  • @animuson, to summarize Shog's post, implementing it just isn't a priority because of lack of value. – Paul Draper May 23 '14 at 1:18
  • @hichris123, true, but delete posts are a) offensive, b) off-topic, or c) obsolete. Why would you really want to see that? – Paul Draper May 23 '14 at 1:19

    @PaulDraper Meh. I don't really see a need to see deleted-comments most of the time... and also, see my first comment: comments are second-rate citizens. They're not designed to stay around long. Therefore, spending time to show deleted ones seems a bit... odd. We do need a better flagging system for comments though. – hichris123 May 23 '14 at 1:23
  • Also, this. – hichris123 May 23 '14 at 1:26
  • @PaulDraper One reason could be that deleted posts contribute to bans; comments do not. Hence, users who have had their posts deleted need to be able to see it to understand the problem, improve them, and get out of the ban. – asheeshr May 23 '14 at 1:36
