The min-instances=0 "fix" is the part worth flagging loudest, it's not a cheaper version of the same behaviour, it's silent data loss wearing a cost-optimization costume. Tasks pile up with zero errors anywhere, which means the failure surfaces as a support ticket about missing emails weeks later, not a billing alert.

The commit-before-enqueue ordering check is the detail I'd have missed entirely. Async execution accidentally papering over that bug via network latency, only to have eager mode "tear the paper off" immediately, is a sharp way to describe how a timing bug can hide behind a slow path for years and then surface the instant you make things faster.

The agent framing at the end is the most useful generalization though, "conventional" and "correct for this billing model" being different things, and the constraint living in a billing console the agent never had access to. That's not really a Celery story, it's a story about where the information an agent needs actually lives.

Good way to put it. The silent-failure part is what made that option especially dangerous, and the agent/context angle is the part I ended up taking away from it too.
