At the time this was re-added, there was concern around how the JIT would handle the system property that enabled it. This shouldn't be a problem, and as such we no longer need to block access to it. The Vanilla Method Profiler will not provide much to most users however there is no harm in providing it as an option. For most users, the recommended and supported method for determining performance issues with Paper will continue to be Timings.
