I question whether articles without conclusions are necessary at all, and the situation you describe is one of poor writing. Say something, then create a headline based on that. If you aren't saying anything, then a bad headline is all that's possible.
So you're saying it's never necessary to consider open questions at all? What if the question was written as a conjecture, then the name of the conjecture was used as the title, would that be somehow better? That makes no sense.
