I agree with you on how it should work traditionally but I have a whole different experience. Once the DME and other modules lose communication from the DSC unit, other electronic protocols go into play. I can't say 100% why this is happening but it is. Some other forum members reported similar activity after coding or disconnecting the DSC unit. They get less intervention but cant completely get rid of it. BMW tells me that other modules can still see data from steering angle sensor and wheel speed sensors although the speedo may not work. Who knows! Lol! All I know is my car is driving just like the new BMWS are behaving which makes me know the software update I got a few years ago changed my setup.
