First, not everyone needs to consider classful thinking, other than on old certification exams. I developed this teaching method while giving a series of courses to a major ISP, which, of course, only uses classless protocols. Second, I do describe classful addressing as a special case, with enforced aggregation to major network "natural masks" at interfaces between different major networks. Students just think of /8, /16, and /24 with restricted subnet masks and no supernetting, rather than class A/B/C (although they are taught to recognize those terms).
