It's 0.3% in my case.

You must be kidding - downloading 1 MB more considering entire distro is

Looking for a real savings?

It would be sufficient to have some rpmdb postprocessing tools to remove
descriptions or changelogs from database, especially for RO medias where
no rollbacks would ever be required.

Unless one wokes up with no privilidged apps in system.
