I guess I don't understand this critique because with a monochrome iconset, I can style them to have the semantic color that's relevant at the time. A dangerous or destructive operation can be made to be red, to indicate the danger of the action. A primary action that I expect the user to do can be made a primary action color. If the icons are _built_ with color, then I can't change the color based on the semantics of how the icon is used. If you give me a monochrome icon that I can style, then I can match the color to the placement and functionality of the icon. So, yes, _in the application_ the icons shouldn't be monochrome. But in the _iconset_ I would generally prefer they be.
