I agree,
The main difference is that this balancing is not driven from device resource pressure, but rather from an assumption of device specific optimization (and also with a specific optimization target), hence a scheduler a user would need to opt-in seemed like a good compromise.
But maybe Ming has some good ideas on a different way to add it..
