It is all about the target use case, uImage and FIT images suit a
useful purpose in an embedded use case. A wandboard is most definitely
not an embedded device. as ARM is moving more and more into general
computing, supporting general computing use cases is needed. all of the
generic distro work I have done is primarily revolving around using raw
images and raw initramfs's all supported fedora systems use a
multiplatform kernel, wrapping it in uImage to work everywhere is not
an available option. You are free to protest, but I believe you are
wrong in doing so.
