It was intentional. The feature counting the faces in Apple
Suitcase font format as if it were TTC had ever been
implemented for MacOS, proposed by Paul Mirror:

2001-10-26  Leonard Rosenthol  <address@hidden>

        * builds/mac/README: Updated to reflect my taking over the project
        and that is now being actively maintained.

        * src/base/ftmac.c (parse_fond): Applied patches from Paul Miller
        <address@hidden> to support loading a face other than the
        first from a FOND resource.
        (FT_New_Face_From_FOND): Updated.

But I sympathize with your dissatisfaction that FT2 provides
no API to distinguish TTC and FOND. Although you already fixed
Pango (and fontconfig?) to distinguish by checking the internal
of the font file (I'm sorry!), do you need any functionalities
in FT2?
