That makes sense to me. However the core problem that came up with the
switch to Quartz seems to be that pTeX does not embed fonts. Should strict
interpretation of document fonts take precedence over usability for
non-english speakers?  Also worth noting is that TeXworks uses Fontconfig on
Linux so we have already crossed this line to some degree.
