But, it seems like that's a simple implementation of a particular framework? I mean, I think they do more than just take a prompt and execute tool calls? But, I appreciate the response and time. Thanks!

Fair, mature frameworks do a lot more. Orbit isn't trying to out-feature them. It's a thinner abstraction specifically for computer-use, where the bottleneck isn't orchestration complexity, it's controllability at the step level. Different problem.
