Given the open source nature of Open Firmware, I'm surprised features like USB boot capability haven't been backported to older New World Macs by the community.

I have no idea if current builds would fit on 1 MB ROM present in New World Macs, or how much headroom there is for deployment of a modern OFW ROM image for even more ambitious projects without resorting to hardware mods.
