Sometimes, a group of students might need to speed up, slow down, or go in a wholly different direction depending on what happened with the previous lesson. There’s a lot of variation between one class of students and another, and teachers are not some kind of omniscient perfect predictor of behavior. And ultimately, you need to cover a whole curriculum.
There is a whole spectrum between teaching centrally dictated lesson plans and individually crafted tutoring, and one of the requirements of teaching is to be able to adjust lesson plans according to reality. We don’t expect software engineers to waterfall every last character in code down to the wire, but teachers are supposed to do this with unpredictable human children?
