Not really, you can defer the flag if you don’t care if the user ever edits their post – if they never do, it will just stay hidden (behind a click to reveal) indefinitely.
The pending flag is a reminder that you are waiting for the user to edit and fix their post, reacting to the PM they got urging them to edit their post to fix it.
Perhaps we could be clearer about that state @eviltrout, when the post is already hidden?
