Laurent on hidden parameters

I saw Laurent's post this evening titled " hidden parameters" and went for a look as I am always interested in anything undocumented and internal. I do not agree with setting underscore parameters unless Oracle say its OK to do so bu8t I do like to know why they are used and what for. Laurent talks about _kgl_large_heap_warning_threshold and __dg_broker_service_names. The second parameter interests me as it can be used to control a broker service for data guard.
