Basically the same as the other comment: First stdlib imports, then remote packages, then local packages. I did this on purpose while touching the imports anyways.

Do we still need the namespaced flag? We could by default create VirtualMachineClusterInstancetype and based on namespace flag decide if we want the VirtualMachineInstancetype instead. What do you think about that?

I'd keep the namespaced flag so it is still possible to create a VirtualMachineInstancetype that does not have the namespace set.
