In general, because the EFI shell sucks and was designed by committee. On a machine with 36 disk drives, it was not easy to find the drive with the UEFI partition that held the firmware update. That's why I mentioned SRM -- the firmware updater built into SRM would try all the drives attached to the system.
What was so painful about updating the firmware via the UEFI Shell? I do/did it all the time this way for the diverse Minnowboard variants and cannot claim that it was painful.
