Why would anyone be worried about the approval of the FSF? If they're being ridiculous and won't approve a shim between proprietary accessibility software and free applications, it has no practical impact. Just don't let them dissuade you and go ahead and write it.
Personally I'm amused every time Stallman / the FSF appear and try to assert control and leadership over GNOME. They have an interesting point of view, but the FSF seems to directly produce very little code so what practical influence can it have?
