Ironically this might actually be worse for mini-itx. In the article's images, everything to the right of the RAM slots is essentially voltage converters. Chop off everything below the PCIe slot to get a mini-itx board, and it's still 30% bigger than we're seeing today. It might allow for a slightly smaller PSU, but you get a substantially larger motherboard back in return as it needs to include voltage conversion for all the peripherals you could potentially attach. If you're making a truly tiny build you won't have much peripherals anyways so all those parts are wasted and something like a Pico PSU might already be a better option today.
