I think it's a great idea and I'm considering building this in lat too. Code embedding models can definitely speed up grepping further, but they still wouldn't help much when you have a business logic detail encoded across multiple complex files. With lat you'd have it documented in a paragraph of text + a few [[..]] links into your code.
