That's bad practice by the firmware authors. (Sad face)

We have enough problem saving ourselves from our own
legacy ABIs without someone handling out more guns to shoot
oneself in the foot with. :(

I'm also speaking on behalf of Microsoft and others in this I
think. In the past we would find Windowsisms in the BIOSes
and get really annoyed that we had to work around them.
Now there are Linuxisms in the BIOS, that's not any better.
