 I completely agree with this statement. And I think that was also the
conclusion from the genimages patch series: it's nice to have something that
allows you to generate an SD card image, but not at the cost of adding too much
complexity to buildroot.

 However...

 Here I disagree, I see no reason to support more than one image generation
system. It's not something that ends up on the target, it's just part of the
build process, so just an implementation detail. It would be like offering the
choice between fakeroot or fakeroot-ng...

 We _may_ choose to switch to a different media generation system in the future,
but that's a different story.
