Put yourself in the thief's shoes... you want to steal a bike because you a: need a ride or b: you want to sell the stolen bike / parts.
You come across a nice shiny Gutterball but it has a Kryponite New York pinning it and it's back wheel to a rack, there are no quick releases on anything, and the front wheel is also shackled to the frame.
Nice score but it would take you all day to cut through those locks... it would be easier to cut through the rack of you had the tools and time.
You are gonna walk away and find something easier to steal.
If you lock up in the same place on a regular basis, just leave the monstrously heavy bad ass lock at the rack you use and use the lesser lock for quick stops.
My strategy looks like this when I have to lock up for extended periods... there are no quick releases on my bike and if this was not taken for demo purposes I would have removed my bags and take them with me.
