Not in my humble opinion.

A battery cutoff switch provides a safety feature from short circuits, or high current leakage that can happen during times of high humidity, and other unforseen situations that, left unattended, can cause fires leading to a complete loss of vehicle(s), including a garage, that's possibly attached to a home, a barn, an out building, or any type of storage facility or other structure. They are also considered as good theft deterrent devices if switch is located in a difficult place to find quickly. They are also very good to have when working in an engine compartment with tools that could inadvertently bridge live wires to ground.
Think about it, I'm sure there are other good reasons for a quality battery kill switch as well, even though you may not have an electric clock draining a battery.
