If you have a course with the following data (from a student's perspecitive): Mar 2, 7, 9, 14, ... Can you be sure that it is really meant as a course that happens every monday and wednesday? No, you'll have to look at your calendar for every date. If you see that the recurrence is every monday and friday, you don't need to look at your calendar, but sooner or later you'll remember. Also, in KOrganizer we also use iCalendar to store the whole calendar on disk, and there we absolutely need a way to store the way in which a date is recurring. Simply discarding all RRULES and using RDATES instead might be a solution for sending invitations, but it's not a solution for storing on disk, and also not for exchanging events between two calendaring applications (i.e. import/export of events).
