Perhaps you only want to sync the files from the lisp/gnus directory
in Emacs to Gnus? In other words, stop syncing files once they get
moved out of the gnus/ directory? Have a static "contrib" directory in
Gnus, or something, that provides the files if they are not already in
the Emacs distribution... Just an idea.
