WSL2 doesn't have Linux roots deep within Windows anymore, it's literally running a Linux VM with a full kernel under the HyperV hypervisor, so it's exactly like DfM (IIRC save for the fact that Windows then also runs under HyperV with the hypervisor sitting on top, Xen-like, and as is achieved on Xbox, and Linux running side by side instead of being handled by an OS process underneath the main OS)
