So couldn't be createrepo actually extended in a way that if it identifies package, which has "Requires: /some/random/path" and at the same time, the "/some/random/path" is actually included in the repository, such file/package would be included in primary.xml.gz? This would help with huge repositories, since there is the highest cost of downloading filelist.xml.
