Hi Behdad, I had that idea before. but I didn't take that way because: 1. Returning available objects with FcStrSet requires the memory allocation. it may be not handy when one doesn't need to have a look into all. 2. There are the use case checking with FcPatternGet*() if FcPattern has the certain objects. this takes a little cost to do with them nor that idea due to the above reason. we could have another API to check it. but FcPatternGet*() eventually tries to find it out internally. so it may be duplicate on work. So as the developer, I personally failed to find any useful. current proposal can do things with same or near costs to current implementation. so FcPatternGet*() might be replaced by them in the future perhaps. I may be missing something else. if I'm wrong, please correct me.
