RFC1519 is 15 years old now. I *still* heard a trainer (in a Cisco class no less) mention class A/B/C in the last few months. Some evil will obviously take generations to fully stamp out.

You need to know something about classes when you deal with Cisco gear because IOS strips prefix lengths on output if they match the length implied by the class.
