I don't see how 3.3 or 3.4 burdens the OS vendor with this utility. 3.3 burdens the firmware and firmware vendor with determining the boot options order, and attempting to boot from each option - with the goal of booting either an operating system or a utility.

And how do you read 3.4.1.2's "default boot processing behavior may optionally occur" because that seems to render everything subsequent as optional for everyone, and still lacks explicit mention that the OS vendor is expected to provide a utility.

Further this seems to present a conflict with the abstraction intent of UEFI between OS and firmware, if the OS is required/expected to produce a utility so the firmware knows WTF to go do with itself.

Conform to the burden placed on it by 3.3. Scan, produce new vendor defined boot options, then attempt to boot from each option.
