Pet peeve: skeletal organic formulas

From the time that I had my first introduction to organic chemistry as a junior in high school (1951), I was required to show all four bonds for every carbon atom in every organic species that was being considered. During my fifty-six years of teaching at both the high school and university level, I required the same of my students. Then IUPAC introduced skeletal organic formulas as a viable representation of a specific organic substance. To me this is just being academically lazy. How do others feel about this accepted practice?
