You don't see them because they aren't there. I can't actually recall the last year there was such a rule. Prior to 2006 at least.

At any rate, fusing/breaker protection is primarily to protect the wire, since it can melt, catch fire, etc. So the manual actually lists what size wire you must use for a circuit off a particular breaker. Or vice versa. Protecting the motor is on your own look out. If you want to power a globe motor off a jaguar with a 40A breaker, you're welcome to. It's somewhat foolish and likely to fry the motor if it stalls, but it won't catch fire, so it isn't FIRST's concern.
