Why? If unneccessary file dependencies are removed the files sizes get
smaller. Of course, yum has the larger benefits, but apt/smart/etc
would benefit from say cutting off half of the file dependencies, too.

The only problem I see is to identify when some file dependencies were
used "unneccessarily". Using file dependencies was never really
preferred over proper package depedencies, so most likely the packager
really wanted file dependencies when he explcitely used them.

That means w/o a proper analysis of what we currently have, we
shouldn't simply ban them. Instead an analysis would show why
packagers used this method and whether we can offer better workarounds
for what they wanted to achieve.
