You missed the point by focusing on the wrong part (containers) instead of the part that's relevant (kill darwin CLI userland).
Imagine the only scriptability you get for the OS is Automator or Shortcuts, https://github.com/apple/container is at best an API at worst a GUI app and certainly not a CLI, and that's it. macOS is MacOS (pre-X). Or iOS-like. Terminal.app spawns a sandboxed Linux microvm. You never see the host from a shell. Dear colima can't even _exist_.
