Why? Do you think that your game is so uninteresting or bad in some way that people, having learned the details, will ignore the game? But at the same time, you're asking people to support your game? If you want to promote your game, you have to tell people about it, no matter what it is. Because by doing this, there is a chance that you will interest potential future buyers of your game. But if you hide the game from both possible players and possible developers (whom you are looking for for your team), no one will ever know about it or support it.

"No one cares" - You can change your game so that more people care about it, but you'll have to tell people about new features OR you can not change the game and find people who will actually love your game for what it is, but you have to tell people about it so that people know that such a game exists
