Open Source hot take: A software project is allowed to be *done*. Not everything needs to add features or rewrite things. You can just be happy with functionality and focus on just maintainance. "Maintenance mode" is not always bad but can just show a mature product.

@tante I remember seeing people complaining on a Steam forum of a game about the game being "dead". It was a single player game and the developer replied that the game is simply done and finished and the reason it didn't get updates for years is that there are no known bugs to fix.
