For what benefit?

Even if to be used in conjunction with --short-circuit rpmbuilds,
%install comes after %build, which comes after %prep. So, all build
requirements must be met. And remember, there's also --nodeps for
rpmbuild.

The scriptlet Requires can be useful for sorting the order in which
packages are installed/updated/erased.
