AR Cloud Anchors in 2018 with ARFoundation

I want to use AR Cloud Anchors on both Android and iOS. Prior to 2018 I could use the ARCore examples based on the Google docs:

https://developers.google.com/ar/develop/unity/quickstart-android

That required installing ARKit/Core individually via specific libraries.

In 2018 it now loads in ARKit/Core via packages and uses the new ARFoundation stuff.

I would like the camera and normal AR mode to use the ARFoundation for a unified setup if possible but still allow the AR Cloud Anchor functionality.

How is that done in 2018?
