Yes, that is very much true. Even if, as some have commented, the people remaining at Twitter lack oversight over the entire codebase to predict that this specific change could have such a knock-on effect, not having testing and staging environments, pushing something straight to production, would give even an inexperienced person pause for thought.
As said, I don't want to speculate whether someone raised their voice on this being a likely outcome specifically, as not having testing prior to release is the much more obvious and significant issue here, driven by leadership.
