That seems to be one of the most dramatically overused misguided statements
bandied about in Linux at the moment, with respect to just about every 
subsystem, and it's really starting to get annoying.

Yes, you should be able to frig with policy decisions from userspace, if

default without user intervention. It's exactly the same mistake apps
keep making, and why half of them are unusable.
