I believe Extra-S was a response to premature Synchro wear problems in the 6MT's.
I somewhat buy this, but if it's really that important you'd think Subaru would make it more readily available and at least educate dealership parts/service departments of it's existence. As an example Subaru LSD oil with part # is listed in the service manual. Nowhere does Subaru make mention of using their transmission fluid, not even a recommendation.
