Cab the only thing I don't like about that is the alternator wire is still hot, the car will die but the alt wire will have power.

With loads of accessories on mine Street car stuff(lights wipers), Fuel Injection ECU, Two Fuel Pumps, two fans, electric water pump, and laptop and phone charging on drag week I like to have a sense wire for the alternator to work off of the power distribution point. It complicates the shut off no doubt but I feel it works better in the end.
