I think it seems a little bit extreme in some ways, because when we talk about Gemini's implementation being simple, the FAQ isn't just talking about structure/readability, it's saying 100-200 lines for a basic client. To me that crosses from 'should be auditable' into something else entirely -- I'm not sure why having a 1000 line client would make this significantly harder to audit, or build, or re-implement in Rust. I'm not sure Rust is that complicated of a language.

But :shrug:, I guess if you shoot for an extreme metric, then you know you'll end up with something that meets all of your other goals as well, so those requirements do make some sense to me when phrased as part an overall architectural stability/reliability goal.
