If you look up battery switches, the instructions call for the switch to be installed on the positive side.
Not hard to tie multiple Positive side wires together, so that's not really a reason.
If the wrench slips and connects both battery terminals, you still get excitement regardless of which side is switched.
On the other hand, if you are leaning against something metal and touch the negative battery terminal (with a negative side switch turned off), you just completed the circuit (frame and metal parts are typically tied into the grounding system. Probably won't die with 12v but not fun.
Generally, the brakes get a dedicated unfused line but for winter storage, I still prefer to disconnect (always do a brake test when pulling out, so if you forgot to reconnect, it will immediately be obvious).
