Using USB micro B lowers the BOM while making the device accessible in international markets (regardless of what your local power is, everyone has USB power adapters). Personally, I'd like to USB-C, but USB-C headers are still hella expensive. That being said, you can power a Pi by attaching the right cables to the GPIO headers: https://www.adafruit.com/product/954 https://www.adafruit.com/product/954 https://learn.adafruit.com/adafruits-raspberry-pi-lesson-5-using-a-console-cable/connect-the-lead https://learn.adafruit.com/adafruits-raspberry-pi-lesson-5-u... Booting from USB required a hardware change, and appears to be available in the latest versions of the Pi: https://www.raspberrypi.org/documentation/hardware/raspberrypi/bootmodes/msd.md https://www.raspberrypi.org/documentation/hardware/raspberry... (Admittedly, it looks like you need a microSD card to boot the Pi so you can reconfigure it this way.)
