The important word here is "still"
I mean commercial distributions seem to be particularly interested in trying out new things that can increase their number of support calls. It's probably just that networkd is either to new and therefore not yet in the release, or still works so badly even the most rudimentary tests fail.
There is no reason to use that NTP daemon of systemd, yet more and more distros ship with it enabled, instead of some sane NTP-server.
