You only need to do that for turns if your bike is three wheeled or has a sidecar that prevents it from leaning, or if you are in the habit of hanging way off the bike in turns, or throw the bike while pedaling off the saddle.
Leaning normally in turns _prevents_ the toppings from sliding. Flat turns, as a car makes, encourage them to slide. Yes, really! This is one of those cases where "common sense" fails many people. Pilots would not make such an error.
The chain deally would be useful for hard stops, but my mind imagines the pizza swinging back down into the head tube when you finally come to rest after a maximum effort stop, and making a mess. For planned stops I imagine you could "fly" the swinging pizza to a gentle landing by modulating the brakes.
