You're missing the distinction. The easy example, but not the best, is
pkg-config: many libraries must be used via pkg-config, so they need to
RDEPEND upon it to avoid breaking binary packages. However, they don't
actually require it at runtime. The other option, which is just about
doable in this one particular case, is to make any package that uses a
library that uses pkg-config DEPEND upon pkg-config.

And an entire tree to update before it becomes meaningful.
