Without this option, UBI images need to be built with --space-fixup [1] so that the kernel can "fix" the NAND on first mount. When this option is used, --space-fixup is no longer necessary because dfu knows how to correctly flash UBI images. However, UBI images built with --space-fixup will still work fine. In other words, enabling this option at buildtime has no countereffects. So there is no point in making it configurable at runtime, if support has been built into U-boot.
