Targeting expresses expectations about an environment. "Do not assume" would be contradictory to those explicit expectations.
It's obvious to me we both can, so why the hell are you wasting our time with useless pedantry?
The article is clearly heavy on the absolutes (eg: "Under no circumstances should you ever use"), and the grandparent comment critized this, and provided a good counterexample.
But you, ironically, chose to assume what the author meant by "do not assume".
