This looks a dubious statement to me, Scribus does not support any
OpenType feature of any kind, OpenOffice prior to 3.2 does not load CFF
flavoured fonts, this has nothing to do with features in the font.
GTK+/Qt apps (AFAIK) treat both format flavours the same way, so does
Windows (you might get different rendering quality, but that is a
different issue).

However I do agree that a mechanism to enable non-default font features
is really needed, and harfbuzz-ng seems to have such support already (as
demonstrated by Firefox).
