Don't know if it is happening now, but it has happened before, and that was when there was still a separate AFT on the Hawk.
You have to realise that there is no 'BFTS' now, as you or I knew it, and that the Tucano course (BFJT) is more advanced the BFT ever was. It's not quite as advanced as AFT was, and not on a jet (if that matters), but it has happened previously, and it did work.
