The question is what "complex" means. Complex for us doesn't mean it's complex for LLM. And vice-versa. So I wouldn't value this approach at all.

I disagree. Much of what makes software complex for us, makes it complex for LLM just as well. E.g:

- a very large codebase

- a codebase which is not modularized into cohesive parts

- niche languages or frameworks

- overly 'clever' code
