The technical challenges in getting memory forking to deliver those sub-second start and fork times are significant. I've seen the pain of trying to achieve that level of state transfer and rapid provisioning. While "EC2-like" gets the point across for many, going bare metal reveals the practical limits of cloud virtualization for high-performance, complex workloads like these. It shows a real understanding of where cloud abstraction helps and where it just adds overhead.

The cost argument for owning the hardware for this specific use case also makes sense, considering the scale these agent environments will demand. Also worth noting, sandboxes are effectively an open attack surface; architecting them not to be in your main VPC is a sound security decision from the start.
