I can answer what #2 is really about because you are right, currently the student does not have access to the course. However what that Idea is requesting is that the student be marked "inactive" (instead of deleted or completed) and for a teacher to be able to view "inactive students" in their gradebooks. Due to certain federal financial aid policies a teacher has to be able to report on a student's standing at the time s/he was removed (dropped, withdrew, medical withdrawal, etc) from the course. Currently, the only way to do this is to reactivate the student in the course which gives the student full access to the course.
