Actual LLM completions are moot. I can convince an LLM its playing chess. It doesn't matter as long as the premise is innocuous. I can hook it up to all manner of real world levers. I feel like I'm either missing something HUGE and their research is groundbreaking or they're being performative in their safety explorations. Their research seems like what a toddler would do if tasked with red-teaming AI to make it say naughty words.
EDIT/Addendum: The only safety exploration into agentic harm that I value is one that treats the problem exactly the same as we've been treating cybersecurity vectors. Defence in depth. Sandboxing. Principle of least privelege, etc.
