"Please split doc into foo-doc subpackage" -> why?

I just recieved one of these bugs (#492446), and I'm not sure why we'd do this for any package. If we split the docs like this: - it would be inconsistent per-package -- so an admin wouldn't know whether a package had docs or not in the main package without manually trying to install a foo-doc subpackage -- they would no longer be there by default if they're needed Hence, why do this, when rpm already has a --nodocs flag and macro that can be used for space savings on live images?
