Without splitting hairs, just to avoid the discussion going in the wrong direction: systemd-resolved is *not* a (DNS) "server" (but a system service). It is a DNS „client“ or consumer and an alternative to glib's getaddrinfo, which solves (or wants to solve) some security issues and provides additional features, such as a cache and split DNS. Using /etc/resolv.conf as a symlink to /run/.../stub-resolve.conf ensures that programs that use the API and those that work directly via /etc/resolv.conf obtain consistent DNS information. Therefore, it is generally a bad idea to replace this symlink.  

Systemd offers a significant improvement in today's network world, where servers often serve both public and private networks, or desktops/laptops are additionally connected to corporate networks via VPN. Therefore, surely not "everyone" wants to turn off systemd-networkd. These are very special cases.
