Yeah, I think part of the problem is that we are trying to deal
with the QEMU equivalent of the following two scenarios:
 (a) "I opened up my PC and plugged in my new PCI ethernet card"
 (b) "I modified my Dreamcast to have a VGA output with the aid of
      a little circuit board and a soldering iron"
and because we're using the same UI for both, the flexibility
you need for case (b) makes it hopelessly confusing for the
people who are only interested in case (a).

Maybe some sort of "Okay, computer, I want full manual control
now" switch? :-)
