Cute, but I think you read it wrong. It would be very relevant to know why someone wanted to talk about this and how it got to the front. There has to be some context, and I suspect GP is intrigued to know what it is.

The only requirement to submit something to HN is "it's interesting". Random evergreen content with no contemporary relevance gets submitted all the time, hence the (YEAR) rule. My 8 year old GitHub repo which hasn't ever been significantly updated gets submitted to HN atleast once a year: https://hn.algolia.com/?q=https%3A%2F%2Fgithub.com%2Fminimax...
If other users didn't think this submission about HN rules was interesting, it wouldn't be upvoted.
