The old behavior is indeed needed for web compatibility. All Array methods are supposed to be generic and I know js libraries use them heavily on NodeLists and ther non Array objects.
ES5, 15.4.4.6, has no type check by itself but it is calling [[ThrowingPut]] which will throw when called on a String. It seems like step 5.d needs to be changed to a [[Put]] instead? I assume we have to update all the other Array methods as well?
