Reviewers, you should now have the option to Bargain bin an item.
Rule of thumb until I can type up something official.
Approval is for add-ons that are high in quality, both in terms of code and user-end
Bargain is for add-ons that are either generally bad and dysfunctional, or have some sketchy (but not explicitly dangerous) code, such as what we saw with someone using eval way too often. It wasn't dangerous, but it was just generally bad practice.
Reject goes for any add-on that has clear malicious code.
For flat-out broken or incredibly inappropriate add-ons, there'll be a system to handle that. It'll be a one-click button press that doesn't require collaboration.
