Most of the industry today is educated to avoid manual hacky solutions on single servers. You need to have fancy UI, frameworks with easy feedback and layers on top of layers who maintain other layers. Cron is an ancient tool with arcane syntax which offer barely anything out of the box, you have to know it and work it to get something out of it.

And there is also the mindset to avoid boring loops, and prefer event driven solutions for optimal resource-usage. So people also have a kind of blind spot for this functionality.
