More productive in what way? Letting agents burn tokens to produce garbage output is not productive. And letting teammates read code that wasn't reviewed by a human submitting it also isn't productive.

If I work with one agent / few subagents on one feature I can steer it as soon as I notice it drifting into the direction of waste. This way I only review the total diff 1.5-2 times. And I also don't waste my own mental energy on context switching between tasks agents are producing diffs for in parallel.

If that’s what you got from my comment then you need to review it again.
