The lack of GPIOs problem in Mini PCs could be solved with a cheap external USB->GPIO adapter such as this one: https://www.hardkernel.com/shop/usb-io-board/
The above board was intended neither for the Raspberries nor for Mini PCs, but the code is Open Source and shouldn't be too hard to adapt.

In the Home Assistant community most GPIO and other duties have migrated to ESP devices and the excellent esphome[0]. I have at least 10 devices around my home and it's fantastic, I haven't wired up GPIO to a Pi or anything other than a $5 ESP8266/ESP32 for years.
Another instance of using the right tool for the job.

Yes, that would likely be an even better and cheaper solution if one doesn't need to drive GPIOs from a complex OS such as Linux which would require a fatter board than an ESP one.

If you haven't tried it you may be surprised by what HA + esphome offers with the 8266/32.
That said, the link you provided is potentially a great add-on for someone who wants/needs the logic available on a real Linux host!
