Why? Zero point really imo. There's nothing you can do as a client playing on a server you have zero control over.. For content creators most things can be achieved by using active script diags and on-frame diags.
I mean this should be something we can enable for the arma 3 client as opposed to the arma 3 server, its not the server which crashes nor is it all players who crashes at the same time. It would be something you would use to debug with like the debug console.
