and _without that_, you shift the burden of having a working power
management completely into the kernel. Forcing the kernel to deal with
completely broken apps. What will happen is that apps developers won't
boder thinking about power consumption since the kernel is "smart"
enough to "fix" their mess.

To me that's much bigger burden to the kernel than the other option is
to apps.
