This routinely happens where I work. To the extent that our UI is this random mishmash of paradigms depending on who was in the room when the decision was made. If I had a nickel for every time I said "if the mechanical hardware does (blank) we should let the user know so they know not to start the rest of the process" only to get blank stares or laughter from the senior engineers, I would retire. "We'll take care of it with training" is a common refrain, as if training can be remembered with perfect clarity at all times.
