I too am religious about recording room tone. I've used it to blend between different takes with slightly different acoustic backgrounds in the same place as well as replace "silence" when I can hear someone in the hallway talking that I didn't catch in my cans while shooting. As well, you can use room sound to tail out behind a scene into the next when you don't have enough practical sound. It's also possible to use your recorded room sound as a noise print for selection in a Reduce Noise filter in audio post.
