Description
In the initial version of the "fix misestimates" automatic stats refreshing we'll have limited observability. We should add more (metrics, logging - perhaps hidden behind verbosity level) to make debugging of the system easier.
This might be closely related to #165272 - ideally, we'd have some signal whether our "fixup" stats are actually addressing the misestimates.
