title: Is it possible to override "main" entrypoint in third party npm dependency?
body: <p>For some reason unknown to me Knockout declares its debug build as "main" in package.json: <a href="https://github.com/knockout/knockout/blob/v3.4.2/package.json#L8" rel="nofollow noreferrer">https://github.com/knockout/knockout/blob/v3.4.2/package.json#L8</a></p>
  
  <p>Is it possible to override this with the production build instead? </p>
