I guess it depends how the excitation to the alternator is derived but it is usually very bad practice to disconnect a battery when the alternator is providing power because the voltage regulation may not keep the output voltage within limits.
Guess manufacturers really need to put safety first and drivers convenience way down the list. For the number of times a disconnect is used, I would have thought opening a door and operating a manual switch wouldn't be too hard.
From that other topic about the recall
Thor sent me the recall instructions today. All they are doing is bypassing the Chassis Battery Disconnect so after the recall is done you will not be able to shut off the chassis battery using the switch. The recall just moves one wire on the BCC under the hood. The instructions are attached.
