At the end of the day, this is really about risk analysis

Obviously something that scores high on both axes
will have me rolling out the upgrades as rapidly as
possible, likely within 24 hours to at least the
majority of the network.

Good for you (not kidding).  Not quite the same on average, as far as I can see.

The other two quadrants are a grey area that
becomes more of a judgment call where other
factors specific to each operator and their
customer profile will come into play.
Some operators may have a high tolerance
for high-probability low-cost problem, while
others may find this very urgent, for example.

I agree with you; however, it's the other quadrant (high cost,
seemingly low probability) which is a real gray area IMO which allows
for collateral damage at a Hollywood blockbuster scale.
