Not at all. As I said earlier in the thread, that seems like a useful
thing to do as I said above (see quote below).
It just doesn't seem like it's asking a lot to have the binding author
clean up from this style of cairo_pdf_surface_create in
It doesn't seem to qualify for the test you proposed of forcing the
binding author to understand complex interdependencies in order to get
a correct binding.
