IMPORTANT UPDATE - The alpha1 release of HAX, based on these efforts, is now available via the HAX project and repo on Drupal.org: https://www.drupal.org/project/hax/issues/2962055
I added HAX to an existing D8 site where I had previously created some nodes from content types with several fields in addition to the body field. While I get the HAX mode tab on all nodes, the HAX toolbar does not display at all so I can't use HAX to add anything to or edit any nodes that have fields in addition to the body field with full HTML. I can use HAX with nodes created that only have a body field (such as the standard basic page). I haven't tried editing an existing node on a D7 or Backdrop site, so not sure if this is standard behavior or a bug with D8?
