I think the question was about packages without replacement.
E.g. a package provided in F22 is not distributed with F23 anymore but
no F23 package provides or obseletes the F22 package name. (Because there is
simply no functional replacement, e.g. the package was dropped because
of lack of maintanance.)
Such non-upgraded package can cause dependency breakage because it can
require an RPM symbol which is not available in the newer Fedora (e.g.
a soname which has changed).
Actually Fedora lacks any systematic approach to this problem. I'm not
sure whether "yum distro-sync" or fedup removes such packages, but
I know some users complained about it.
