Not really. A question that’s simply closed as a duplicate isn’t going to get any answers, and the answers to the original question, while they may have once been reasonable enough to be accepted, might be outdated.

Languages move on and add features, and closing any question as a duplicate precludes new, modern features that provides better way to answer the original question.

A lot of content on SO is dated to say the least, precisely because reputation harvesters with a dated knowledge of the language are overly keen on closing questions.
