Right, maybe "dependency chains" is the wrong term. What it means is
that this is the total number of packages (which are probably shared
with others) necessary to support this package.

In today's Server WG meeting[1], we came up with an approach to
removing these packages from the default install while not losing the
functionality they provide (hooray for auto-installation).
