1) We support HMR
2) We have different approaches.You can split your code as much as you like, creating bundles using arithmetic instructions http://fuse-box.org/#arithmetic-instructions
3) WebPack tree-sharking works poorly. We are working on a universal solution that will support CommonJS tree-shaking.

No, We are not confusing it with anything.
There is a great PR going on. We are going to introduce HMR plugins, that will allow users to specify their own logic. Without altering the code.
