This is my take as well, just because you can get away with something doesn’t necessarily make it desirable to maintain or extend, and I honestly cannot imagine the effort in terms of labor hours that you’d have to go through to develop something like this compared to just plugging in an off-the-shelf scheduler to something slightly more sophisticated like k8s or even just a worker-and-queue system. When you’re talking about platform engineering to solve a problem that a relatively extensible Celery service could do (and have tests and such), I have no idea how the former could be “less work” or cheaper in the long haul.
