I think it all boils down to this question:

Do we want Fedora to provide full support for the TrueType standard
(actually file format is much more appropriate) or not?

method to another on a per-font basis. But to move on and completely
disable such a feature (bci) is a hefty price to pay. Would be nice if
we could build a kind of a whitelist where bci would be used against
this and that font and disabled otherwise.
