The difference is that without UEFI you need DOS on the USB stick, not just
your BIOS flash tool and image. Ever tried booting modern server-hardware
under DOS and running BIOS-update tools from that?

No, we need to come up with an environment that is able to run the flash tool
the manufacturer provides. If this tool is for EFI shell, this is easy.
Getting a DOS tool to run under DOS booted from a USB stick... your mileage
may vary.

You lost me again.

I didn't mean to say that EFI might fully replace your rescue disk (whatever
it looks like), it certainly doesn't. But in some at least for me quite common
cases where you just want to get the system booted it serves that purpose and
relieves me from having to boot the rescue disk.
