I propose to move the capability from the Suppress Stack Trace Plugin into core and clean it up a little bit. The existing plugin behavior is to show the trace to administrators and to connect it to a specific log message for other users. I propose to retain this behavior.
Jenkins has seen a significant rise in security-conscious use since this plugin was created. Jenkins should be more secure by default. While showing the stack trace isn't a security vulnerability, not showing the trace is standard, expected industry behavior.
