Hands on testing of the 29W USB-C charger and the USB-C to Lightning cable, confirming the use of USB-PD 2.0: https://www.macstories.net/ios/testing-apples-29w-usb-c-power-adapter-and-ipad-pro-fast-charging/

Good to know the 29W adapter will still fall back and provide older Apple proprietary USB power charging at the 12W rate. I wonder if it provides the other boosted USB charging variants if plugged into say an older Nexus 7 tablet.

Dan, have you done any write ups on possible security concerns around USB-PD 2.0 spec over USB C cables?
