They don’t need to do that, they are already providing only federally mandated info via obd port if you use generic obd tool. That’s the nature of modern diagnostic protocols such as UDS, while being very universal and easy to implement, it has a lot of magic constants defined by specific manufacturer which they don’t need to disclose. I personally don’t think it’s that bad with BMWs, inpa and ista are everywhere and don’t need an internet connection to work.
