GDI do support using the correct font family names for fonts. However, 
applications often won't support such fonts because of how they select 
fonts (e.g. will only consider a font to be bold or non-bold, without 
any distinction on exactly how bold or light the font should be). There 
are other parts of Windows, e.g. USER, that is/were more limiting 
though. Consequently, font vendors break the windows family name of big 
families in order for them to be functional in all applications. Still, 
there are room to get the font selection/matching correct with GDI on 
Windows for CSS. It's not trivial though, and many apps won't bother.
