I still need to make this work / compile with all the feathers, sounds like a good software project for my vacation, right? The PCB could get got an update too, all 8 inputs and 8 outputs on a header.

After I read 2.7V on the VCC pins it finally made click - the VCC pins weren't connected to the 3.3V pin, but got voltage through diodes on the enable and SPI pins. This made me so happy, that I bought some new boards and parts and I will make this a tindie product at one point.

I did something I haven't done before on this board, a matrix to reroute pins with solder jumpers. Otherwise the board looks fairly simple and boring, not much to route on it.
