> We are currently collecting stats for the size of preemptor {{BiCache}} ({{reservation_cache_size}}).
We could additionally collect cache expiration stats to monitor overall preemption effectiveness.

> Currently, we have no visibility into whether reservations made by preemption are actually
consumed or simply expire.
