And I see no reason why we should provide such a interface. Nobody force you 
to use it and if you don't touch it, it do whatever the default on your 
machine is (I assume ondemand gov.). But there are always users (and 
usecases) where e.g. a single laptop user or a desktop user want to be able  
to incluence the settings without touching sysfs (where you need to be root 
to change something).
