This is quite cool! Any PCB designer that needs a lot of power should just use this design and hopefully the world will eventually settle on using micro USB for low power and USB PD for up to 100W. I am currently thinking of making a device that has a PCB, and one of my key requirements is the use of micro USB (5V 500mA) precisely because designing power circuits and distributing DC adapters is a major cost.
