I wouldn't prefer that, but I'm also not as convinced that Cryptocat is as "clearly broken" (i.e. plaintext is trivially recoverable) in its current state as a lot of people on here are. Most of the attacks that I've seen so far were against the group chat implementation, which, granted, is significant, but not against the primary component, the OTR chat.

I think it is somewhat naive to believe that any mechanism other than a one-time pad will absolutely keep your communications safe, and that it's a little dangerous to insinuate that Cryptocat leaks information about the plaintext but X or Y doesn't.
