Adding accessories this late will take a lot of effort from the gani team, to go through every single animation, add the sprites, then put them in every single frame of every single direction of every single weapon, as mystical dragon said, it will not be worth the time and effort that'll be put into it, also as he stated (i'm not sure) they will have to go through every single customs uploaded and delete those containing accessory-looking items on them, such as backpacks and scarfs, also a new upload approving rule which is so much to do.
