I assume because of the baseband stuff to be FCC compliant? Last I checked that meant DMA channels, etc. to access the real phone processor. All easily activated over the air.

I don't think the FCC requires DMA channels. That's done out of convenience because it's how PCIe works.

Indeed. The only reason this is not used by customer support for more casual access, firmware upgrades and debugging is a matter of policy and the risk of mass bricking phones and as such this is not exposed to them. There are other access avenues as well including JTAG debugging over USB and Bluetooth.
