Good question. I think it’s the additional security? From [1]:

> Hyperlight is able to create new VMs in one to two milliseconds. While this is still slower than using sandboxed runtimes like V8 or Wasmtime directly, with Hyperlight we can take those same runtimes and place them inside of a VM that provides additional protection in the event of a sandbox escape.
