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.
