This can run very efficiently in a Virtual Machine.
So many virtual machines run complex kernels and security features, for just one application listening on some port.
While this is a toy operating system for some standard Desktop scenario, it is already promising for another scenario, with the move of services to managed containers (serverless) in the cloud, with huge overhead (relative to the tasks performed) and slow startup time.
Then, this can be the AWS Lambda runtime for Rust (add networking and database libraries), and it will be faster and more efficient than other Lambda implementations for the other languages.
