Hi Chris - this is not a dupe in HN's sense of the word. Please see https://news.ycombinator.com/item?id=43303443 and https://news.ycombinator.com/newsfaq.html.

On HN a repost counts as a dupe when a story has had significant attention in the last year or so. But if a story hasn't had significant attention yet, reposts are ok.

https://news.ycombinator.com/item?id=43292977 certainly didn't get significant attention, so the current submission was fine, and certainly not a [dupe].
