... there are a few maintainers.
They control things like which projects are part of Fedora (not which
files of those projects though), teams and Releases.
So the correct person to contact is the developer of the
project/package which has old files, even if the package belongs to a
larger project (hub as you call it) like Fedora? In the initscripts
example, I should talk to the initscripts developers, right?
