Whether or not your exit routine is doing anything useful can only be
determined by examining the routine and understanding the exit.

That means someone has to find the source code, make sure it's the actual version running, and then be able to understand it well enough to make a decision about whether the processing is needed or not. I've seen sites where even step 1 is a problem. So maybe a more realistic approach might be: Turn off the exit, wait to see if the phone rings, and be ready to put it back.
