Sure, if you use it directly. The biggest complaint about webpack is it’s hard to configure.

We configure it for you. You don’t need to think about it.

What other problems does webpack bring in your opinion? File an issue and let us know: https://github.com/facebookincubator/create-react-app/issues...

Again you've suggested the introduction of problems without mentioning a single one. I'm not saying you're wrong (because I don't know what you're saying yet), but I don't think you're adding much to the discussion here.
