Lonely Setting

I know a serious complaint Minecraft has been getting lately that the world feels too full, and that it doesn't feel lonely enough. We already have a button to toggle generating structures, but that's more for creative mode if you don't want to be bothered. In survival, with generate structures off, there's no way to beat the game, and you're locked out of a whole lot of content. What if instead, in addition to generating structures and not generating them, there was a lonely mode that made structures like half or a third as likely to spawn? This would obviously be optional, but I think it would be A. a fun challenge, and B. give players the option to choose how they want their Minecraft world to feel.
