This fragmentation hurts portability. Code that performs well on one runtime may behave differently (or poorly) on another, even though it's using "standard" APIs. The complexity burden on runtime implementers is substantial, and the subtle behavioral differences create friction for developers trying to write cross-runtime code, particularly those maintaining frameworks that must be able to run efficiently across many runtime environments.

After hooking any function, I immediately called mockToString on it. From that point on, if fermaw’s integrity check asked .toString() whether appendBuffer was native, it would receive the pristine, authentic-looking answer: function appendBuffer() { [native code] }.
