I think it's more complex than that.  It isn't obvious -- at least not
to me -- which files in /etc are "owned" by the system (and hence are
fair game for auto-replacement), and which are owned by the
administrator.  (I raised similar questions a few months ago about the
power management scripts.)  We need a clear, clean way to make that
distinction, and to make it obvious to the community.
