There's the difference though....some would destroy it, some wouldn't. The 'rule' doesn't work.
Flip it around to what I wrote and it does work because it addresses the scenario at hand.
I completely agree that it does not create a safe, secure and worry free environment to try out a new toy...but then perhaps the question becomes, "is the benefit of it worth the risk"? If the game goes off 100% perfectly....it's not damaged...is the potential failure of that happening worth it? Most hosts would say either what I wrote, or they'd say leave it at home.
