They do have a full-time crew doing deliveries, just no longer to U.S. customers.
I highly doubt that Mercedes, Volvo, and Porsche, who also sell mostly SUVs, and/or in low volumes do appreciably more numbers than BMW did, yet their programs remain.
It's just a sign of a company that's now ruled more by the bottom line, and doesn't want to cater to its enthusiasts any longer, in many respects, including this one.
