I don't have the personal investment that you appear to have with Bun, but why does this matter? Do you scrutinize the rest of your dependencies this way?

Much of working in the JS / NPM ecosystem is already pure faith on un-vetted dependencies, and this appears no different pre or post LLM rewrite. If it satisfies the intended goal and API contract it originally did, is there any difference? Were you carefully reading the original source code before?
