Strongly disagree on the SSH example. Security warnings should be a little more alarming than just "Continue yes/no". Asking whether they are sure they want to continue has added context to make someone think twice about whether they are really connecting to the correct host. Likewise, repeating the host address again after confirmation makes an error more likely to be spotted if it's off slightly (think along the lines of spaced repetition helping memorise things).
