I assume it is because there is no universal concept of "page scrolling". If you look closer scrolling page wise is a much more complex topic than scrolling individual items. For example, some applications will not show anything that has been shown before a "page down" while others will show some amount of the last content (e.g. to improve reading experience). Then, do you measure "page" in terms of fixed size units or fixed entries? With the former you might get half shown entries at the top if the window height is not an exact multiple of the item height while with the latter you always start at an item boundary.
