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.
