I would like even more events added to Moodle so that other plugin developers can better tie into Moodle. For example, we are adding a grade_grade_updated and grade_item_updated events that the activity completion component should be using, rather than inserting itself into the gradebook directly.
But that is a core hack we needed to do. With the Logging improvements spec that was developed at the Hackfest, it is proposing to use the events api to replace the add_to_log method calls. So any work you can do with tying into the events api can only help later down the road.
