> The person best qualified to assess the relevance of any previous answers is often the OP.

The purpose of having the answer there is not to solve the OP's problem. It is to have a question answered that contributes to the canon of work. This way, everyone can benefit from it.

> What would be the harm in pointing out previous answers but leaving the question open to further contributions?

Scattering the answers to functionally the same question across the site. This harms everyone else who wants an answer to that question, and is then subject to luck of the draw as to whether they find the actual consensus high-quality answer.

You might as well ask: what would be the harm in putting a comment in your code mentioning the existence of a function that serves your purpose, but then rewriting the code in-line instead of trying to figure out what the parameters should be for the function call?

> Closing duplicates makes as much sense as aggressive deletionism on Wikipedia.

This analogy makes no sense. The Wikipedia analogue is making page synonyms or redirects or merges, and those are generally useful. "Deletionism" is mainly about what meets the standard for notability.

So instead, it's considered preferable that the best possible answer never be allowed to emerge, unless by sheer coincidence the best answer just happened to be the one that was accepted the first time the question was asked, several years ago.

There's really no need for us to rehash SO rules/policy debates that have raged since day one. The verdict seems to have more-or-less delivered itself.

What? No. The canonical target isn't closed. So go write the new answer there. The answer acceptance mark is basically irrelevant, and the feature ill-conceived. Except usually there are dozens of answers already; the best possible answer has emerged; and people keep writing redundant nonsense for the street cred of having an answer on a popular Stack Overflow question. > The verdict seems to have more-or-less delivered itself. We do not care that people don't want to come and ask new questions. There are already way, way too many questions for the site's purpose. The policy is aimed at something that you don't care about. The result is a "verdict" we don't care about.
