I read though half of the article thinking "This is like Honeycomb[1] way of thinking" without realizing it was written by Charity Majors[2].
So, keep in mind that the article is biased towards their business - they are in the Observability realm - and the long-term goal is making you think that you have to achieve super-deployment speed, and that involves deploying to prod often, and have a good system (Honeycomb) to know at any moment what's going on in production with real data. And if it breaks, you just have to quickly rollback.
Aaaand, I buy that. I mean, I think she has totally a point on this: having a safe and quick way to production that leads you to be confident on rolling out things quickly because you have a safe and fast path back, it's a good thing for any software engineering team/organization. It's not easy to go there and you still obviously need tests while developing/integrating, you need canary tests, you need to program in a defensive manner etc etc, but not being scared of sending code to prod and "test" how it will really hold the production pressure it something I'm personally trying to achieve at $DAYJOB.
