Comment 2 for bug 633692

You claim "17% of requires metadata" as if that were relevant. The actual
reduction in _HEADER_ metadata and *.rpm package sizes is far far smaller.

And if you _REALLY_ want to reduce rpm _HEADER_ metadata size, compressing headers will
lead to significant savings that far outweigh filtering a few Requires:
dependencies from *.rpm packages.

There's nothing whatsoever stopping you from filtering whatever you choose
to include in repo-metadata, where a a reduction in primary.xml _IS_ likely
significant. But that is no rpm issue.

The real flaw in yum is repeatedly downloading repo-metadata as a monolithic
blob of _EVERYTHING again and again and again and again. But that (of course)
is irrelevant in a RPM bugture/featlet report, isn't it?
