ZGC cpu metrics in logs

    Wondering why zgc doesn't print cpu metrics like below

[2019-10-23T17:42:48.539+0800][0.959s][info][gc,cpu      ] GC(118)
User=0.00s Sys=0.00s Real=0.00s

For any other garbage collectors it is printed.
Is this avoid because ZGC stop the world pause is always in milliseconds?

Just curious why this was not printed for ZGC alone.
