I'm convinced that we have no clear understanding of "duplicate" here. I recently had a question here closed because I asked for the "closed by" message to not credit votes to those who did not cast them. It was claimed that my request was a duplicate of another request that desired to see an exhausted list of vote-types in the "closed by" message.
The two are not the same. "Please correct this" vs "Do it this way".
This is not a preference-issue. It's a correctness issue.
"Closed as not-programming-related by Jonathan Sampson" is incorrect, when Jonathan did not vote for that reason.
Suggested-alternative, show only the names that voted for the majority option, or show no names at all.
