Well, yes. That's part of having a solution that addresses the whole
community and not a subset. Linux is already full of things that trade
off benefits for one platform against costs for another platform.

As noted in previous apology, I was speaking over-broadly. However, as I
said, we currently configure out cpufreq and ACPI support, among other
things, so they represent wasted effort from the particular perspective
of our products. I was speaking rhetorically - just saying that the work
done on cpufreq and ACPI was "wasted effort" in exactly the same sense
that work spent on supporting the PM needs of embedded devices would be.

Thanks - I can agree with that!
