Funnily this description isn't really helpful IMO. I would have expected to learn about the difference between USING_MOVE vs USING_OFFSET from the help texts. But they appear to be identical.

Sure, but it wouldn't hurt refer to it.

MCUboot expects slot0_partition and slot1_partition to be present in DT and application
will boot from slot0_partition. MCUBOOT_BOOTLOADER_NO_DOWNGRADE should also be selected
