From the description of the recommended tool it sounded to me like something that you use to deterministically generate code from a spec, which you could then modify if you like. That would be the same kind of dependency as the LLM workflow you describe, except that the abstraction is well-defined in a way that the LLM is not. Whether it's good or not is a different question.
That would be nice if it were the case but from what I can gather from this interesting dependency graph, there's a hard dependency on its renderer and schema.
