For example detecting where the device is and adjusting the current in separate coils accordingly? I don't buy the explanation that this is about interferences

For example detecting where the device is and adjusting the current in separate coils accordingly? I don't buy the explanation that this is about interferences. It doesn't seem like an insurmountable problem to me.

C(32, 3) is 4960. That means almost 5,000 different interference patterns to deal with. Since every manufactured device will vary (since each of its 32 manufactured coils will differ slightly from the next), that's 5,000 calibrations that need to be done on every single manufactured device. And that's best case, assuming (for example) that calibration is a single metric per coil over time.
