Systemd timers are designed to replace crontabs, but that's not what
cron.service is.  cron.service runs an actual cron daemon.

hobbit:~$ systemctl status cron
● cron.service - Regular background program processing daemon
     Loaded: loaded (/lib/systemd/system/cron.service; enabled; preset: enabled)

I don't foresee real cron going away any time soon.  If systemd wants to
create an alternative to it, that's fine, but people know cron, they
like cron, and they *trust* cron.  Systemd timers don't have any of those
benefits yet.
