Pick an choose, most features are opt-in to avoid bloating the final image.

Some people are not interested in networkd and prefer to use connman,
NetworkManager or other tool.
Note that networkd is not wifi aware, but does observe interface state
changes. For wifi you'll need wpa_supplicant to actually drive the
process of joining networks, while networkd will handle DHCP part.

resolved is not enabled by default either. Even when enabled, it's not
really useful without the nss-resolved piece. I've posted a patch to
OE-core [1] that would set up /etc/nsswitch.conf properly but I wasn't
merged.
