I'd never argue for building your own - just for using something simpler than Celery

It's not so bad now as CI/CD, Docker etc have made complex deployments easier to handle. But back when I was wrestling with Django simply deploying Celery on a new host could easily waste an afternoon and all those dependencies made me very nervous about the overall complexity.

I still weigh carefully anything that adds another long-running process or non-Python dependency to my sites.
