Wondering if an idea like this would work:

Bundlers like Webpack already import JS in a modular structure. I'm wondering if we could do some profiling into popular npm module combinations (I know many people using React + Lodash + Redux Router, etc), bundle them up, and have Webpack load in those combos from a CDN via <script>?

Now this would probably require some work on webpack's end (the __webpack_require__(n) would have to be some sort of consistent hash), but at least everyone who blindly require('lodash') will see an improvement?
