I can't answer your question specifically (someone else may have to do that), but I will say this: cron is the natural "scheduler" on a system and if you're doing anything that's supposed to be in the background or "scheduled" it's nice to put it on cron. Easier to find for other programmers, universal scheduling system, etc…
Additionally, you could use Celery to do work. Schedule a start script as a
cronjob and put whatever kind of job you want work to be done for into Celery.
That's how I do it at least.
