These binary checksums will change with every single kernel
release/variant. I'm not sure I see the point of using an always unique
binary checksum vs a %{version}-%{release}?

If kmodtool starts providing this by default, then there would be no
need for the Requires: v-r in the policy. I suspect you'd need to
convince the kmodtool author(s), not me. :)
