No. I've seen many oopses which were completely harmless (few processes died, who cares? :-).
I advocated putting 10sec delay after oops. It is good so at least you can see the oops and you can remeber IP if you are fast enough ;-). Much better than quickly rebooting machine. If you extend this delay to 10min, user will have plenty of time to copy data onto paper ;-)))).

Unfortunately, there were cases when this destroyed valuable data.
