You can still make them! Even on your own if you have a moderately good PC.
It's just that it's kinda useless, and finding a good image for the background is hard. You need something the AI can use to set the brightness, but no matter if it's bright or dark it must still be recognizable as part of the background image. So the image needs to be something without overarching structure. But you need overarching structure to fool the viewer into believing it's just a normal image.
