Once I got used to it it was pretty fun, which is what I was afraid of, because it takes time, it changes controls making going back and forth between games harder, and it doesn't add anything material to the game, if you see what I mean, plus the novelty has to wear off eventually. It's a somewhat similar problem to having sprint and having it last a long time or be infinite. It looks like crouch jump will be back regardless though: https://twitter.com/JoshingtonState/status/551444162122248192
