God forbid the already unreviewable -710kloc/+1mloc change get any bigger!

Sure, but that's kind of orthogonal. Imagine doing this by hand I still think going like-for-like with the Zig, even if that means a lot of unsafe, is a good approach.

But I suppose if you are already using LLMs it's more reasonable to try and go from Zig straight to Rust with no/minimal unsafe.
