And yes, plenty places are not at the point where this is a "press button and done" activity, even if it should be. (e.g. pretty much everyone who is buying any kind of "appliance" and isn't just running open-source stuff now knows to go check with vendors)
(As an example/thought experiment. I make no claims about the vulnerability at hand.)
I don't work in a regulated industry where it's required, but we do similar with a proper change control process and there's not a single individual that's authorised to perform changes without oversight, (even if that oversight from senior leadership comes retrospectively).
