I don't think AI can be completely banned, even if they wanted how will the judges even be able to look through everyone's code and say if that is AI or not, same for Idea generation, AI does generate some decent ideas but at last its the developer adding their own spin and tweaking stuff to make it work.
I think the point is not to allow AI generated assets like art and sounds which are clearly AI, but helper tools like background auto fill and stuff they don't generate art do they, they just help in the process of making the final asset
