I believe that the subpixel rendering is actually enabled in the rasterization step, in libXft or in cairo. Subpixel rendering *is* a defacto setting on most major distros, wherever it is enabled (freetype, xft, whatever... not totally sure). Gnome and KDE's font configuration areas each have options for subpixel rendering. But redirecting my request to any of those (freetype, xft, cairo) developers will not solve the issue with Wine, because Wine does not respect your system's font settings, whatever they may be.
Wine doesn't render fonts on its own, it uses Freetype for that task. Subpixel rendering (or ClearType) must be done by the fonr engine, not by a client application. And since subpixel rendering has been disabled in Freetype due to patent reasons this bug is both invalid and wontfix.
