The question isn't whether or not you'd get the same line count with a non-LLM tool. The question of whether or not it's vibe-coded depends on whether or not the committer actually reviewed and understood the new code. And with a 75k line difference, that seems unlikely.
The commit would look exactly like that if it was a 100% deterministic transpilation (like Golang did with their original C implementation?).
This is obviously very different from that, but the way the commit looks doesn't make it so.

Why? Do you think large changes not made by LLMs are also reviewed line by line?
Just another Monday in 2026.

I'm sure it will be called Systems Programing . Because Rust.
