^^ I doubt that as long as people start getting KYC in bunches, this is a topic that is required, plus there are many other casinos that require KYC as well if anything special happens, it is just a precaution thing that casinos do to both save themselves from legal trouble but also help you as well to get rid of legal trouble, KYC for no good reason would be a bad thing but KYC for a good reason is a good thing.
So, I would say do not really care for the ToS version of "what could happen" and just focus on what is going on, they are not asking for it and they are not making a deal out of it neither, they just put it up there for show and for future and that's it, move on until you see people start getting KYC left and right, you can worry about it when/if it happens.
