that is the point. rewrite is fine when - you take your sweet time doing that - you still know full well the codebase

that will ensure the new codebase can still be well understood and can continue to grow in foreseeable future

or you can just vibe the whole experience if it is a legacy project with all the specs and edge cases known.

since bun rewrite is neither of the case, it will be a crapfest soon enough.
