I saw a new question yesterday which was closed as duplicate, because there is another similar but different question where one answer also answers the new question. The relevant part of the answer is only a side note in my opinion and wasn't required to answer the old question.
I think that's not a valid duplicate, as it would still be a good answer for the old question if that part is removed and there might be better answers which focus on the new question.
But there are other opinions, therefore I'm a little bit confused. Is that a correct use case for the dupe hammer?
Example: Why SSL uses a third party (certificate authority) yet SSH does not (P.S.: I'm aware that it might be closed for another reason.)
