I thought so too, but they don't: systemd-cron uses run-parts for
cron.{hourly,etc.} too. It only generates individual, parallelizable
systemd timers for scripts in cron.d, which in general run on their own
independent schedules anyway.

If you want this, the way to opt-in to it is currently to add a native
systemd timer, and make the traditional cron script a no-op on systems
running systemd (to avoid doing the periodic task twice). For example,
apt and man-db have both done this.
