A question (Is post-COVID flying more dangerous?) that seems to be answerable only with subjective answer has an open bounty (on friday the 7th of august 2020). I would like to add it to the "close vote" review queue as "opinion-based", but I get the error message "open bounty & cannot be closed". Reading the comment, it seems I'm not the only one affected by that feature.
There could be other older questions that did not received attention at all, with no answer, and that should have been closed or deleted long ago. But as they never get activity, nobody see them anymore. Such a question can suddenly have an open bounty while it still should be closed.
Why does this feature (unable to close a question with an open bounty) exists? In which cases is it useful? Do we need to propose a modification on this feature to be able to close question while a bounty is open?
