Have I said power doesn't matter on AC?
Do you agree that a datacenter has different performance vs power 
tradeoff demands as a battery driven mobile device?

Back to the topic:
As you did not answer on my (several) sysfs knob request(s), I expect
you agree with it and will add one.

It's not only for real usage, but to give people a chance to easily
test and get feedback on different HW.

Thanks,
