There is no difference between adding new loop and adding new shelf. In both cases controller is going to see new disks appearing on some SAS adapter. If anything adding new loop is less disruptive because you do not need to temporary break path redundancy for existing disks.
I do not know if this is explicitly mentioned anywhere as special case; it sounds to me more like "do not put pets in microwave" sort of things :)
