I don't really think there needs to be a new buttton/statuses... "Consider"ing nodes in the types of cases you're talking about seems like it owuld work fine.

It might be a useful addition if the "Hold" button was nothing more then a big red blinking flag, designed to point out a problem to would-be-approvers to wait a little while untill the author cleans it up -- but if your intent is that the hold button puts a block on it untill the author petitions, then we might as well use the existing consideration options, which allready exists, provides everyone an chance to weigh in on the issue, and keeps any one person from beating nodes he has a personal dislike for -- and putting the burden on the author to request that they be revived.
