The northern hemisphere schedule breaks down so that the OCR must be held in Jan/Feb... so the boats can get to the US after the EU season... and then to the Southern hemisphere if needed... and then back to the EU for the season over there for the next cycle.
Worlds are scheduled with the grade I events in mind. The elite circuit is controlled by the Grade I events.
Hell... the proposal is for ISAF to actually take over the Olympic class's actual World Championship.... It just eliminates the amateur class leadership this way....
At the end of the day... I listened to an old guard Olympic sailor who would always advise.... trust me... you don't want your class to be Olympic. I joined the class... watched the BS... THEN I understood what she meant. It was a great experience... BUT... there are just issues.
