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

[Andrew Lutomirski]

I have a tendency to upgrade to a new Fedora release as soon as it's
final, and I sometimes upgrade even sooner.  ISTM that the official
upgrade process is almost always broken, often for known reasons.
Should one of the criteria for releasing Fedora N+1 be that a
fully-updated Fedora N must be able to successfully complete 'fedup'
or whatever the current preferred upgrade program is?

(FWIW, the current bug is particularly nasty -- fedup 0.7.0 apparently
can't actually update anything, and the sequence:

 - Install fedup 0.7.0
 - Try it and watch it fail or hang
 - Update to fedup 0.8.0 from updates-testing
 - Run fedup

ends up downloading all rpms *twice* a sucking up a correspondingly
immense amount of disk space.
