:-) Honestly, FontConfig seems to work quite nice, but it lacks
someone who is taking care of, for example, by improving the
documentation or adding features.

Well, I consider FontConfig as *the* interface to the fonts of an
operating system, and there are situations where a substitution is
simply the wrong action.  I would prefer if there were functions which
returned an empty list in case the match isn't exact, say.

Maybe.  However, then the documentation is not correct or imcomplete
since the result is simply surprising, and this is always a bad
sign...
