What you really want/need is to make the PackageIndex support
retrieval from multiple index urls; the PackageIndex itself
aggregates available packages from sources such as the local file
system, -f urls, and an underlying package index. So having multiple
aggregators would duplicate processing, and deprive you of a global
ordering of package precedences.
