Agreed.
Though you're missing thing - automated bug report system generate
-huge- amount of noise. Lowering the signal-to-noise ratio to something
usable is -very- labor intensive.
Far worse, people (who send such report) tend to forget about them (as
opposed to manual bug reports) making them far less effective.

So, question is:
A. Who will do the heavy lifting of developing such system?
B. Who will triage 1000's of orphaned bug reports.

Assuming, of course, that you can pin-point what exactly broken
evolution within the 150 package update push.
Will you roll back all the updates? Only updates that had -something- to
do with the breakage? (Let alone kernel updates that can more-or-less
break everything in sight...)
Oh, and what do you do when at least 50% of these updates are
high-priority security updates?

Say-what?!?
Are we building a second Vista here?

/+100.
Though this idea has come up a number of times before. AFAIR it was
dropped due to space considerations and possible kernel-version
problems. (In theory, you may need a different rescue image for each
installed kernel - unless you plan to keep the original kernel)

Not sure what that means.
You can always enable updates-testing and selectively install what you
need.

Yes, but in the is case, the UI has a profound influence on the why
Fedora works.

On a side note, I'm not sure what you're trying to achieve by this last
paragraph. But if you intention was to start yet-another-flame-war, I
have a bad feeling you're on the right track.
