Posting this because I saw a discussion in another post and figured it could be worth sharing somewhere that isn't going to seem argumentative like replying to a comment.
Valve has actually completely removed a functional case and key system before. Dota 2 used to have treasures with corresponding items and rare unboxes, as well as corresponding keys (just like CS). They removed both the treasures and keys, and changed keys to a redemption system where you could select which treasure you wanted to unbox. It's ancient history compared to probably a lot of users on this forum, but it is actually not unprecedented and is something that could potentially happen in some form to CS.
