If it was purely about saving costs why even use USB-C, though? They could have just said that a 3A micro-usb supply is now required for USB power. The Pi4 isn't actually using any of the increased power delivery provided by USB-C PD, which is in the higher voltage range, after all. It just wants 5V 3A, which micro-usb can certainly handle as well (there are a variety of such power supplies for previous Pi's in fact).

Seems like a really questionable cost-savings maneuver to switch to a way more complicated & expensive connector for nearly no reason, and then penny pitch on one resistor.
