In the bad/fun old days of extremely small on-call loop, a less clear/organized escalation chain, and fairly "roll your own" per-team tooling, once in a blue moon a whole business unit would be down because 10k machines were crash-looping and you just needed `if (NULL == ptr) return;` on like one line to end the carnage. There are exceptions to every rule I suppose.
But in 7 years at FB I think I force slammed someone else as reviewer with merely their verbal approval in the middle of the night 2 or 3 times, and never after like, 2015.

That is probably for the best.
