well, but people usually don't ask for making e.g. the print feature optional because they don't use it and want a lean browser... i mean, you need to draw a line somewhere, sure, but different people will draw it differently.
Funnily enough the platform also provides a screenshot system. From another comment it seems like this was driven mostly by user feedback from Windows users, because the ~3 different ways of doing a print screen on Windows are not sufficient and they demand more.
Btw. the screenshot tool of Windows can't capture a webpage properly, only the visible area.
