@zentol I'm not entirely sure whether reviewable makes things better or
worse wrt reviewing. At least I can no longer respond to individual comments
directly from github.
You're right with both comments. I'll remove the
`CheckpointingStatistics#generate` method. Moreover, I'll move the
CheckpointStatsCache out of the legacy package.---
