I came here to post the same thing. But this is addressed later in the same paragraph:

> But hopefully better development practices, with a human in the driver’s seat, and a focus on reducing technical debt and writing idiomatic Zig, mean that in a few weeks or months there will be a presentable codebase that serves as a drop-in replacement for Rust Bun 1.4.0.

So the intention here is simply more steering. Or perhaps better steering (code structure appears to be a matter of taste... I had a very perplexing chat with a friend yesterday who insisted that four backend processes were required to serve a single HTTP request...)
