Slowing things down implies selectivity. If you have time to talk about fewer topcis, you'd better be quite sure they're more important than the ones you've omitted. It's a high-risk endeavor for the instructor. What if you pick the wrong topics? You have to have a lot of confidence in your judgement to teach a slow class. Much safer to cram as many topics as possible into the semester.
