"hifi sourcemaps" don't work on a new Ember project about ember-cli

[jagthedrummer]

I got hifi sourcemaps to work in my new app by doing this:

yarn add --dev @embroider/core @embroider/compat @embroider/webpack webpack

Then updated ember-cli-build.js to look like this:

'use strict';

const EmberApp = require('ember-cli/lib/broccoli/ember-app');
const { Webpack } = require('@embroider/webpack');

module.exports = function (defaults) {
  const app = new EmberApp(defaults, {
  });

  return require('@embroider/compat').compatBuild(app, Webpack, {
    packagerOptions: {
      webpackConfig: {
        devtool: 'source-map',
      },
    },
  });
};

After updating my real app to try to use embroider it seems that some add-ons may not play nicely with embroider. Is there any possible way to get hifi sourcemaps to work in a non-embroider app?
