Will -rep ever come back?

[JDBar]

I understand now why -rep should stay removed, but... What about neutral rep then? I'd like to be able to give feedback to someone or at least post a public warning on their profile in case they're an untrustworthy member, so other users would be able to check their rep and see reviews on that user. It'd be more useful for scammers and such rather than immature members, but you could also publicly give them a suggestion to straighten up in return for a a change from neutral rep to +rep. This way there'd be no -rep and there'd still be the incentive to stop acting like a child.
