What I find ridiculous is the assumption that kernel should provide good
power management even for badly written applications. They should work,
of course, but there's no assumption that the kernel should cope with
those applications and provide good battery usage on those cases.

You can install and run anything on the device, and they will work as
they should (they will be scheduled and will be processed) but you can't
expect the kernel to prevent that application from waking up the CPU
every 10 ms simply because someone didn't think straight while writting
the app.
