> We currently have two MergePolicy implementations that are wrappers around another MP: {{SortingMergePolicy}} and {{UpgradeIndexMergePolicy}}. A {{MergePolicyWrapper}} will simplify building additional such wrapping MPs by delegating all method calls to the wrapped instance, and allowing implementations to override only what they need.
> Also, this issue removes the {{final}} modifier from MP public methods so that they can be delegated properly. See LUCENE-7008 for a test failure that uncovered this issue.
