I can testify that this is a Big Deal. I manually upgraded to NPM 3 for my own minification/bundling system because the old behavior was breaking dependencies (one package passing React objects to another, and each one depending on different versions of React). Part of the issue is that the old method of dependency resolution, especially for peerDependencies, was just awful.
