The red tags/moderator tags/status tags — except for status-review, perhaps — on Meta indicate that a mod has considered a feature request or bug and made a decision about how to handle it. In other words, they tend to equal "this is the official answer from the admins."
Over a hundred questions in the Unanswered list are marked status-completed right now, mostly quick bug reports that don't require long explanatory answers. Depending on how you look at it, they'll never be answered, they can't be answered and/or they've effectively already been answered. Could questions with red tags be filtered out of the Unanswered list entirely?
