I don't think it is ever a good idea to diconnect or re-connect under load. Some times it can't be helped but I always find these situations to be scary.
That is odd, the NEC allows disconnect switches and breakers to be the controller for a motor. Are you suggesting the NEC is allowing 'scary' installations?
See 430.83(A)(1) and (2).
No matter where you open the circuit it is done under load, regardless of it being a switch, contactor or relay.
