Hi Dave, I've had this type of discussion at a previous telco company and the only explanation I ever received regarded ground potential differences between equipment through the mains (as we have discussed in a previous thread).
And I always seemed to win by saying that if everything was chassis grounded, then that would be the path of least resistance anyway. At this other company, we shifted from isolated grounds to everything grounded to the chassis and I never saw any of the problems the designers said would happen. In fact, immunity robustness increased. I'll admit that this was with a limited number of products. And I'm sure others here may have different exeperiences.
