That would be true if people really needed to know what /dev/sr0 is, but for 
the most part we shouldn't need to.  Once upon a time, because of some 
little quirk with a Palm Pilot, I needed to know something about the 
/dev/sg0 device, but when things are working properly all you should need to 
know is /dev/pilot (I think - don't use it anymore!).  Similarly, for most 
of use, all we should need to know about the CD/DVD drive is /media/cdrom.  
I'm pretty sure I've never needed to know that /dev/scd0 links to /dev/sr0, 
let alone what sr0 is.
