The most broken thing with the PS/2 connection was if I plugged in a keyboard/mouse after the system booted it wouldn't be recognized and I had to reboot.

I also imagine if you decoded how much of the USB protocol is needed to operate say a USB-to-PS/2 adapter and keyboard, that would be much smaller than the spec. Don't need power delivery or video or higher operating speeds? Things get much simpler.
