Code

It'd be useful to be able to disable the express serve-index middleware, which generates directory listings when you view a directory that doesn't have an index.html file.

// webpack.config.js
module.exports = {
  // ...
  devServer: {
    serveIndex: false,
  }
}

For Features; What is the motivation and/or use-case for the feature?

This option is required to be able to do SSR for the root page with webpack-dev-server in an after() middleware using the serverSideRender option, as otherwise an automatically-generated index page will be shown instead.

I'd be happy to put a PR together for this change if it's likely to be accepted.
