Yes and no.

Yes, for code that uses fontconfig. But in the real world :(, not all
code use fontconfig (or at least in all parts), example of this are
software that used the mentioned xpdf (splash engine): poppler*, kpdf, ...

   182    // if we have the FT2 bytecode interpreter, autohinting won't
be used       
   183  #ifdef
   184    if (FT_Load_Glyph(ff->face,
   185                      aa ? FT_LOAD_NO_BITMAP : FT_LOAD_DEFAULT))
   186      return
   187    }

If Debian GNU/Linux have this, then no issues have with it :)
