If we are register votes yet, here is mine. Have -Wuninitialized be a very simple detector, which is either in the front-ends or in the middle-end so it could be shared (just like -Wunused). Have -Wuninitialized=2, be the current -Wuninitialized. Have another option to detect variables which are set but their values are not used (this was in one of the -Wuninitialized bugs and has been asked before). The EDG front-end implements this option.
