I've seen often new users' questions get into hold because of off-topic, unclear and trivia.
What if we use separate tag for those questions so we can easily find what was gone bad and ultimately try to either bring back as a good question or just remove it? There are huge number of those on hold questions are being neglected every day and they keep pushing down by other questions often with popular tagged question.
what I suggest is, that if we use a separate tag, either moderators and/or experienced users can give little bit more attention to those low quality questions and make something good out of them? it's just an idea.
