Re. NTP: Timekeeping is rather essential in lots of applications - like, for example, transit operations, where I currently spend my work life. An accurate, accessible central clock tends to be a rather important system component. And we're talking concerns in the range of seconds. When you start getting into serious real-time systems (laboratory instrumentation, utility operations, warfighting, ....) - yeah, NTP servers start getting really interesting, to a lot of people.
As I've already said a couple of times, systemd does not force a particular NTP implementation on you. It comes with one (timedated), and has a utility to manage it (timedatectl) but the admin can install and use a different one if they like. The only thing that has changed recently with respect to that is that timedatectl can no longer be used to manage chronyd or ntpd. -- Jeff Ollie
