If I recall correctly - and I might not - the process found places in the test suite that were wrong or lacked clarity, and the suite was modified slightly in a few places to actually fix things that needed fixing. I don't think it was a broad enough change to actually significantly affect the coverage to a real degree, but then again, that WOULD be a good thing to dive into the PR to check - and as I've pointed out, I'm not a Bun user myself, so my main response to that is a vaguely-interested shrug and a nod towards what seems to be the bigger issue: the use of AI to do things performatively.

In what sense was Bun's rewrite performative? If I recall correctly, Jarred deliberately tried to fly a bit under the radar to prevent the inevitable outcry

In the sense that while there was a positive outcome ("We moved to Rust, which solved our issues with Zig no longer accepting AI-assisted content" - a projection on my part, but one I think makes sense) without an actual contribution that one would expect.

It's in Rust! That means Rust's memory safety applies! ... except as a direct port, it doesn't, it's got Zig's memory semantics in Rust-shaped code. As others have pointed out (including me, FWIW) that's something that can change... but it's not a simple thing to accomplish, and it may ALWAYS be a Zig-shaped skeleton in a bag of Rust.
