for starters, if you want the DNS info embedded in it (and other stuff
like that) then the in-kernel one won#t give it to you.

duplicated from what? I mean, the whole thing is a duplicate of
NetworkManager if you so will, or of dhclient, and so on. Nothing
networkd implements hasn't been implemented before. it just integrates
stuff better, that's all.
