We have different notions of "covered", then. When I teach algorithms and introduce quicksort, the majority of the time is spent discussing strategies for choosing the pivot. I expect none of my students to implement a quicksort with bad pivot selection; if they do, that's my failure as a teacher and definitely failure in "coverage" of the algorithm.
