Huh that's interesting! I found celery to mostly match my expectations. I used it in a couple of django apps. My only real foot gun was around having to set an EAGER setting for local development or tasks never got executed.

How did you find your expectations and celery's actual semantics to be different? I'm trying to document well and it seems like I might have some implicit assumptions that I could make explicit, but I don't know what they are since they're already in my head and matching celery it seems.
