I can't imagine it's a technical limitation, just that it's expensive. I don't know if this is true for the M135i, but at some point (can't remember the year), BMW started welding the ring gear in the 135i diff, so you can't just swap out the components; you have to replace the entire diff and ring gear. It ends up costing close to $2,500 for a LSD, and that's just for the part.
