You might use it if you get ATC saying "Unknown traffic 12 o' clock, avoiding action turn left heading 090 degrees"
Then you want to get the autopilot out and bank as much as you can to get round away from the traffic, passenger comfort goes out of the window just as it would with a TA alert, GPWS warning, or stall warner, you want to whip the aircraft in as tight a turn as you can.
I've had this twice now, rather good fun.
Pushing things to the limit in the sim also helps with unusual attitude recovery.
