While Doubleclick does not require GWD, they definitely push you towards that solution, and have no active forum for Studio creative. The Doubleclick Studio dynamic template files are from 2014, and from what I can tell, any newer template activity in the database is all GWD. That being said, there is live chat when you are logged into Studio, and they are very helpful, just don't mention Animate.
I was able to determine that Animate CC canvas exports can play well with enabler.js, using z-index. You just have to change your images export path to ./ as Studio does not work with subfolders.
