Contrary to the many naysayers about the need for this "unneccessary" expense (which I DIY anyways), the only reason BMW dropped the break-in service from their recommended schedule was because they went to a "free" maintenance program for the first few years/mileage starting around year 2000 or so I believe. Once BMW starting picking up the tab, they dispensed with the the break-in oil change and introduced "lifetime" fluids such for such things as transmission, differentials, power steering, and transfer cases.
For leaseholders it's all irrelevant, but for long term owners a conservative maintenance protocol can be very beneficial (and cost effective for DIYers). Ask most experienced techs about what they've seen in their shops over the years.
