I completely agree. I have strong doubts that ObjC is used anywhere in the exotic hardware area. Like if I look at the embedded field where mostly other processor types are used, I don't see why GNUStep would be of any use there. And if, they can still use an old frozen gcc version if they are old. I must admit that myself I use GNUStep without any desktop in mind, basically Foundation is what I need for my server applications because my code is heavily written in ObjC and especially because of its nice features such as ARC. So for me going back to gcc is absolutely impossible. So besides Intel and ARM architectures, what is really used out there in the field? .
