I'm a bit concerned about the global option. I'm not quite sure how
many CFF fonts are broken at this point and how long font authors will
take a time to fix. in worst case those global options gives bad
effects to fonts well-maintained and the maintainer take a quick
action for, to work around for bad fonts, which isn't well-maintained,
outdated and so on. plus, there are no syntax so far to let
applications know the kind of global things in fontconfig. if it can't
be improved, I suppose that feature would rather be implemented in
others.
