We also store counts by type to further enable other performance optimizations in later patches.
At the time this was re-added, there was concern around how the JIT

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.
This will force the saves to spread over multiple ticks even when many
players auto save interval is aligned, avoiding spikes on large servers.
