As I already stated, if it turns out that things will be simpler with
this separate, we could easily make that change later. I do agree with
Marcel that that is unlikely though.

networkd should be usable in a minimal environment, like an initramfs.
However, we also target other simple setups like
virtualization/containers (inside and outside, which is what this
feature is mainly meant for).
