I'm ok with teaching it to beginners to explain where we came from but 
that should be it.  It should be made excruciatingly clear in the 
training that it's no longer done that way because we found a MUCH 
better way of doing things.  That said I still occasionally refer to 
networks in classful terms and I can think of several network engineers 
who have years of enterprise experience that still don't understand CIDR.
