My comment would be that, while U-Boot images /run/ on embedded systems, people do not necessarily /work on/ these images /from within/ said systems; indeed, work on such images, and more generally, development around U-Boot, is performed on development systems, not on target systems. Besides, in many cases, the image was actually built from files available -- even from files themselves built just before putting them together within the image. Apart from very specific cases (tweaking the initrd in an existing image comes to mind), I don't see the point in taking images apart when you can simply build them the way you want.
