I agree with the Kman. Back when V20 went online I posted a number of hidden config options to the exploder list. Well after I did, a manager from PTC called me directly and said I should have not done that. As it was explained to me, hidden options are put there mostly for PTC Developement's purpose or to fix a specific problem a customer is having. Their use is not supported by PTC and if you run into problems using them PTC won't be liable. Of course, now they are like old friends. I only use a couple of hidden options in my installation for the reasons mentioned by myself and the Kman.
