Doesn't this have more to do with Babel and less to do with Webpack? I think this originates with how Babel treats ES6 Modules differently from CommonJS, and if you were to instead do:

  const foo = require('./bar').foo

it would keep the name the same?

There is a better explanation with a partial solution.
