Couldn’t you use the same workaround as with FreeType fonts?

In the early days of Cairo, these were not reference-counted either
(they are now). But cairo_ft_font_face_create_for_ft_face cannot be
changed to add a call FT_Reference_Face without introducing a
backward-incompatible alteration in the semantics. So the caller has to
resort to the user-data dance documented here
<https://www.cairographics.org/manual/cairo-FreeType-Fonts.html#cairo-ft-font-face-create-for-ft-face>.
