Maybe I'm really dense, but this is just instructions for agents on how to write code, whatever that code looks like.
What is the difference between asking an agent to write these new two DSL's and asking an agent to create or customize a django template, or whatever?
I know the job market is tough, but devs are not working on the user side of WYSIWYG email editors. They were creating templates before, and they are doing it now, why would they use this?
