popularity-contest already gathers this data as part of the data that it
sends to Debian.  Maybe a tool that operates on the data that it gathers
and tries to find packages that aren't being used to give a list to the
local administrator would be an interesting approach for this?

Ideally, it should filter that list against the dependency structure and
only report leaf packages.
