A typical use case is using quick_cache as a HashSet with an eviction mechanism. In such scenarios, the value is usually a zero-sized type like PhantomData.
Since there's no need to update the stored values in these cases, concurrent management mechanisms such as PlaceHolder are unnecessary, thus reducing memory overhead.
