Good to see we pick those nits and refactor as a small step one by one. Can you elaborate more about the context, particularly answer those question

1. what's the current design
2. what's the issue with current design, why it's a bad design needs to change (usually you can say something are coupled together, which against XXX princinple or make us less flexible to handle the potential scenario change or feature requirement)
3. what's the new design
   if you answer Init integration with form-editor #2 very clearly, you don't have to talk too much on this question, because you solution should be clear.
