I don’t see it in the hardware design, but from a software perspective the groundwork is there for modularity. Offloading the core compute to the PC frees up onboard processing to run peripherals like full color front cameras (onboard are black and white / IR) and more advance proximity detection, hell hook up lidar and go nuts with full body tracking.
That said, all of that would depend on decent I/O. 2x USB4 ports would go a long way.
