Please reread https://news.ycombinator.com/item?id=9775868. It says one year since it received significant attention, not one year except when a massive chunk of features and content is added.

And as you can see, the criteria is “Whether or not it contains significant new information (SNI)” which is indeed exactly the opposite of what you are saying.
