TFA has a few red flags exposing a lack of knowledge in the subject matter. First, the fuse used on the Pi is actually a polyfuse, a type of slow-resetting PTC thermistor. A high current causes a temperature rise that changes it into a metastable high-resistance crystalline structure or something, and it resets over a few hours or days with the power disconnected. It does not need to be replaced. The polyfuse also causes a voltage drop that can noticeably cut into the Pi's very tight margins, so there is a reason to deliberately bypass it. Second the capacitors do the same no matter where the power is from. Presumably the capacitors are placed near the chip. It does not matter that the schematic shows them between the power source and the chip because that is just showing logical connectivity. Placement of the TVS diode matters and that's presumably near the USB port. Third none of this is about powering through the GPIO pins. It's about powering through the power pins next to the GPIO pins.
