> As a result of OAK-3348 we need to partially rework the memory estimation step done for
deciding whether compaction can run or not. In {{oak-segment}} there was a {{delta}} value
derived from the compaction map. As the latter is gone in {{oak-segment-next}} we need to
decide whether there is another way to derive this delta or whether we want to drop it entirely.
