I wonder this too. I prompted Opus 4.7 to generate some Python threading code for me. The code to run the sub-thread looked like this:

    def run():
        with contextlib.suppress(SystemExit):
            do_thread_thing()

    threading.Thread(target=run, daemon=True).start()

The model's response: "Honestly? Cargo-culting on my part. You should remove it."

I had some shell scripts littered with `|| true`, which was obviously obscuring real errors everywhere. When I challenged the model, it gave me the same "cargo-culting" answer.
