Xinerama extension does not return DPI values for each physical screen

The DPI value of different xinerama (i.e. physical) screens may differ enormously though to my knowledge there is no function yet to return a DPI value on per xinerama-screen basis rather than for a whole 'screen' comprising of one to many physical monitors stitched together by xrandr. I am talking about the default functions XDisplayWidth/Height[MM] and missing corresponding information for the xinerama extension: There is simply no such member in xcb_xinerama_screen_info_t. I believe desktop environments could profit a lot from an updated xinerama interface.
