Chrome Web Store has the opposite view: your extension can get rejected if it has more than one purpose. Our extension got taken down that replaced all in-page ads with ads from our network while paying the user in a certain Ethereum token for every ad impression they see. The ostensible rejection reason being that it both replaced ads & served as a crypto wallet.
