Perhaps the issue author thought the member was given this name because only privileged/blessed developers get to use the “cool stuff” of React. They likely don’t understand the reason why the concept of access modifiers exist in many programming languages. Namely that (good) library authors will do everything possible to avoid breaking the public API, which can be seen as a “promise” from them in what can be relied upon, while internal/private members offer no such promises and the library author can feel free to change/remove them as desired with no prior notice.
