I wonder what the additional layer of virtualization changes with respect to this in a project like this one: https://github.com/dockur/macos
The unattended setup is a large improvement, which also begs the question: Mac OS doesn't have an unattended.xml alternative for its installer?
macOS has unattended setup options via MDM or Apple Configurator…

A closer comparison here is Lumier, which provides a "Docker-like" interface to spin up VMs with a noVNC server: https://cua.ai/docs/lume/guide/advanced/lumier/docker
The key difference: dockur/macos uses QEMU+KVM, which only works on Linux hosts. It can't run on macOS hardware since Apple doesn't expose KVM. See: https://github.com/dockur/macos/issues/256
