Should a working fedup in Fedora N's stable repository be a release criterion for N+1?

[Andrew Lutomirski]

OK, so I'll re-ask my original question.  Fedora 20 was released with
a broken update path from F19.  Should the release criteria be
amended?  This particular issue would have been avoided if F19's fedup
were frozen along with F20 and if all of the destined-for-stable
versions were tested together as a release criterion.
