In what way? What files would be missing?

Well, since you do have a full build at kernel package creation time
the current procedure seems fine, only the final packaging needs to be
changed, e.g. introduce kernel-headers/devel[-smp|-<other flavour>]
packages on par with the kernel[-smp|-<other flavour>] packages, and
have the latter have a symlinked /build/ to the former.

Each kernel has its own kernel-devel/header, and yum/apt/up2date etc
need to be tought to handle these new multiple packages just like
"kernel" itself.

You don't want to shove all headers in one rpm, as this will again
make it harder to build custon kernels with their custom
kernel-headers/devel packages.
