Decoupling strategies
ResourceTemplates
Points the runtime to yaml files that allow author to add pre-written versions of blocks. For example, a “multiple choice” template for ProblemBlock. I believe they are all in xmodule/templates.
for each class, is templates_dir_name defined?
No → Easy-- no templates! Safe to remove the ResourceTemplates mixin.
Yes → Harder. ??
Open question: Do the React editors use these?
