*Gets the heavy chains out to drag this back on-topic*
Another way to perhaps look at it is the class structure employed by some clubs of beginner, intermediate and advanced classes.
The beginner classes (up to around 7th kyu) almost exclusively revolve around the fundamentals of the system.
Intermediate classes (~6th to 4th kyu) build on that and mostly assume that the students are competent or at least familiar with the material covered in the beginner classes.
Advanced classes (3rd kyu+) will assume competence in the fundamentals of the system and at least familiarity with the material covered in the intermediate classes.
So if the system included throws and takedowns (and therefore hopefully breakfalls), the breakfalling might normally be expected in the beginner classes and if you go to an advanced class they will simply assume you are competent to land safely, and if you are not then you shouldn't have gone to that class.
Before anyone shouts at me that karate is only punching and kicking

then you might be taught correct technique for punching in the beginner classes, and be introduced to concepts of timing and distance in intermediate classes and employ the techniques in sparring and with focus mitts and bag work. The intermediate level students get the multiple-technique combinations and in the advanced classes the combinations become "simpler".
All of this maybe contrives to take you to BB where although you are doing advanced classes you realise that you have only just reached the beginning and now it perhaps is time to take your knowledge of how to punch and kick as you start learning karate.
