Review comment:
       We could add a comment about why we have split the tests. That could be a hint for someone trying to unify them, or extending any of them with more cases.
   ```suggestion
   /**
    * Test read repair after partial deletions when the cluster nodes are in different versions.
    *
    * This test and {@link MixedModeReadRepairWriteTest} are separated to avoid OOM errors on CI (see CASSANDRA-16237).

Review comment:
       Nice utility function. Maybe we could have a variant asking for a range of versions, like everything up to 3.x, that could be used in `mixedModeReadRepairCompactStorage`. Not saying that we should do it in this ticket, though.
