QoS isn't necessarily about throwing packets away.  It is more like
making voice packets 'go to the head of the line'.  Of course, if you
have saturation, some packets will get dropped, but at least the voice
packets won't get dropped since they were prioritized higher.

That's generally true as well.  But why would you need it?  What's the
advantage to be gained in using QoS to throw away packets, when the
packets don't need to be thrown away?

Go ahead and deploy it.  It's easy and works well.  It 
certainly doesn't
need anything like QoS to make it work.
