Given monitor on dumpling has

fc: 505 ; lc: 168872; latest_full: 505 ; diff: 168367

This leads to a significant amount of time spent on start rebuilding all those versions each time the monitor is restarted.
Currently we will only update the latest full version record (a "pointer" pointing to the latest full) on trim, which is a problem on an unhealthy cluster (once again, because we will rebuild all those full versions on start, despite they already exist).
