Yes, I understand that application-level exceptions can sometimes be "budgeted for" and a certain amount of them is acceptable.

Hardware metrics on the other hand should IMO be monitored and alerts should be in place for when things go wrong, as the consequences of it could potentially be way more serious.

Things look very different when you have as much hardware as Google does.

When the CPU hits the thermal envelope regularly and throttles itself that seems like a serious enough problem. Sure, if it's a normal part of cost optimization, then it won't stand out.
