Hi,
It is for any competent shop. You should always disconnect the battery when doing any electrical work on the car. This is especially true if you are replacing any electronic component. If there is a B+ circuit, it can arc or power spike when you attach the connectors if the battery is hooked up. It doesn't take much to fry today's microelectronic components. Better safe than sorry...
Happy Motoring!... Jim'99
