There is a whole slew of these that have been here since OS8 or 9 that haven't changes. When they first went to OSX they were missing but came back right away. Control+command+shift+4 is so engranded my fingers at this point with another shortcut I do on average a dozen or so times a day.
I don't know when Windows "Was snuck into these shortcuts" but just noticed that when I took a screenshot.
