How to get Essentials to use Quantization?

I have just watched an ESRI presentation on best practices for Layers and Service Types.

This has made me want to review our current implementation and take advantage of more feature service capabilities.

One of the things that they discuss in the video is the use of "Quantization" to improve performance of Feature Services, especially with respect to bandwidth.  It is meant to be enabled "out of the box" and indeed if I spin up a really basic Esri Javascript application I can see that Quantization (and PBF for that matter) are defaults and they "just work" without any special configuration.

With Essentials however I see that it is not using quantization (uses JSON as well) when retrieving features and I was wondering if there is a way to enable this is the HTML5 Viewer.

This is the video for anyone interested:
