I would propose to either document that `PrintNMTStatistics` prints on checkpoint, or make it have several modes (0 — off, 1 — print on exit, 2 — print on checkpoint, 4 — print on both exit and checkpoint), or add a separate `PrintNMTStatisticsOnCheckpoint`. The reason why I am proposing this is because I believe we had a related request from community for this somewhere, so it would be nice to have this documented.

OK, while I've used this for diagnostics on ZGC it would really make sense for its own PR.
