My CS education is going on two decades old, I think it was decent, and the ideas in this article aren't something that was taught back then in any class I had.
For the most part, it was the other way around, we mostly learned abstraction, so the lessons in class focused on how to encapsulate and hide state. At a higher level than that, education really focused (and still does, I think) on engineering for functionality over engineering for performance.
In some sense, the problem with APIs that allocate is larger now than it ever was before, and growing larger. Data sizes are bigger now, and memory pressure relative to what the processor can do is going up.
