Agreed.

I seldom see people actually talking about class {A,B,C,D,E} networks as 
such.  It's almost always a reference to the size ~> netmask ~> prefix 
of a network.

You can safely say that 72.234.7.0/24 is a Class C /sized/ network. 
While it happens to be in the (former) Class A IP /range/.  But it is 
most decidedly /not/ a Class A /network/.
