First, there is the use-case of add-in card, where it's impossible to
use UEFI-based update, as much as I understand, as the BIOS isn't
expected to expose an ESRT entry for it.

Even for built-in controller, my impression is that most OEMs use a FW
update application (running on Windows) and are not publishing a UEFI-
based solution.
