no - I think it'll be hard to argue why we need 20K pkgs in a single
repository. Or hell, why we need 20K pkgs AT ALL.

1. this is what he asked on yum-devel list. I told him there was the
beginning of an implementation but it was never completed. He made it
clear on yum-devel, at least, he didn't have the time to do any work on
this - just that he wanted to tell us how he felt.
2. you still have to get the original metadata
