This is exactly the case here.

The author of Bun is a Thiel Fellow, so he's already been trained in The Way.

People are trying to wash away the recklessness of this rewrite by applying engineering principles the author their self didn't apply. It's like trying to make sense of a certain president's words. There is a lot of missing analysis both before this rewrite, during it, and after that is missing. And given that Zig and Rust can interoperate with each other via C, it makes a wholesale rewrite even more bizarre.
