Another idea: What about separating between three close “types”:
- Duplicate: This question has been answered already. Links to an answer, that one might be later inlined.
- Off Topic: This question does not at all relate to the topic of this site. It is unsalvageable and needs to be deleted or migrated. (exceptions may apply, such as e.g. historical locks)
- Needs Your Attention: This question has problems that make it impossible to answer, right now. It needs to be edited by the author in order to make it answerable. (Show a list of problems closers have identified)
