While Google's lack of consistency in icon sizing is frustrating (though it is getting better, slowly), real world usage does look much better than that, as the icons are centred rather than placed on a baseline. http://i.imgur.com/CYUVTw8.png

That being said, I do think that rounded squares are an important part of iOS's design and that style icon is associated with iOS, so I don't think it should be changed.
