For example, RobotoMono font looks quite weird without antialiasing (hinting?), LiberationMono looks good. With .nfont package for RobotoMono I've added "RenderHints_hack = 0x010203;" and after user copy this package into it's ~/Library/Fonts directory everything works as font package creator think should be better for user. Liberation Mono has no "RenderHints_hack" at all. Everybody is happy. If I want RobotoMono to be drawn antialiased at any size and other fonts non-antialiased at size less then 12 I need to add configuration (system or user) on font install. Sure both ways has right to live but fontconfig way breaks NeXT/Apple style of doing things that GNUstep follows to.
