In https://github.com/babel/ember-cli-babel/pull/460, the structure of the returned object by buildBabelOptions was changed in order to update broccoli-babel-transpiler to v8. However, buildBabelOptions is a public method and these structural changes were causing issues under Embroider and might also cause issues for ember-auto-importhere. Even though the next release is breaking, reverting these changes seems like the safer thing to do.
