No, the hardware folks have good reasons why they want things to work a certain way. I am mostly objecting to the fact that the model of the current streams proposal is heavily biased towards a fairly narrow use case and closely tied to how current generations of flash controllers are implemented. I would like to see a bit more abstraction put into the model so it is less "controller with N flash-channels and anemic ARM core" centric. That obviously means more complexity in the controller design, hence the pushback from the vendors. However, I think it'll be worth it in the long run. -- Martin K.
