We find that as the workloads grow, it becomes a bit more burdensome to maintain. Did my job run correctly? Where are my logs? Do I need to make my box bigger? Do I need to pay for a VM when my workload only runs once a day? How do I get my code from GitHub onto the box? etc.

All of these are solvable, certainly. Just as Heroku removed the need to set these things up, so too does tasker but purpose built for batch processing.
