Personally I don't think it's unnecessary to add normal maps or any other visual effect for indie games. If it's suitable for the game you're working on then why not?
The thread was started by somebody wanting to know more about normal/bump/dot3 mapping and I don't think it's very constructive to tell them it's "totally unnneccessary for indie games".
