I wasn't thinking here. It doesn't make it useless at all, it is very well possible to implement ssh in a way that the private keys cannot be printed to screen, and it would still be usable. In fact, I was thinking of setting up something of that sort for gnupg, where I want a user to be able to sign and decrypt things only as long as they have access to some account.
