Loader vs ES6 Classes

In practice we've found that we rarely use the "new Loader(hooks)` option and instead this is more common:

var loader = new Loader();
var loaderFetch = loader.fetch.bind(loader);

loader.fetch = function (loadRecord) {
  // do something
  return loaderFetch(loadRecord);

This way we can think of each modification to the loader in isolation and we can use the same code to modify a custom loader instance and to modify the System instance.
