I would prefer to see this as a configurable option. I have systemd
installed (because it's not really optional to have a functional desktop
on Linux) but I want to restrict it to starting and stopping services,
not performing the tasks of cron. cron is portable across a wide
variety of systems, including Linux variants (and WSL) that don't use
systemd, and I prefer to use more standard tooling when possible.
