Just that only one SIM socket is connected to onboard socket, for obvious reason. WiFi device control signals are also defined in the spec, but again not every socket have these pinouts connected. Care needed, yes. But abuse? probably not. The spec is not intended to make device/slot universal among all implementations like PCIe slots do. There are more than main PCIe signals to take care of, and that's left to system integrators on purpose. The name is just misleading. Probably it should not have been called PCIe Mini Card, but "Versatile Mini Card for PCie, USB, UIM, WiFi" instead. ;) (and yes, mSATA is not in the spec. That's another story.) -Jia-Shiun.
