I also want to address another point. The design of the BMW clutch is not really that unique. I have been working on VW cars for a while now and VW used the same transmission concept (maybe still, I have been out of the game for a while). Germans love their backwards stuff. The clutch components are more or less the same as oil head except they put ring gear that the starter engages on the clutch cover and not on the flywheel (funny looking). The pressure plate is bolted to the crank and the "flywheel is bolted to the pressure plate. Here are the components.
You can see the plate that the push rod engages(bottom right) that is very similar (same function as in the oilhead)
I have done 20-30 of these clutches and none were lubricated and none had spline wear. the input shaft did however go all the way through the clutch plate. Here is a quick picture. So there is no reason that the concept is wrong since it has been used for a while on millions of cars. Just to address the concerns of those that say "I have never seen the transmission without pilot bearing."
You can see the long push rod that goes all the way back to the cam (throwout bearing is under the cam) that is actually connected to the clutch lever (cable actuated).
