Oh, I believe a lot of things are broken.  I'm just not
sure I agree that replacing everything at once with
a new set that passed a couple of tests together is
the right way to deal with it.  In particular it doesn't
make any sense to me to have to replace a kernel and
device drivers that have worked flawlessly on my hardware
for the last year or more with some wildly different
version just to get a new version of evolution and
some other desktop apps.

You seem to be forgetting that with fedora, the users
*are* the integration test.  And for people who have their
own apps, the OS distribution is just supposed to supply
working unix-like interfaces.

Well, yes - the unix-like interface was pretty well
designed by about sysvr4 when linux started the attempt
to emulate it.
