Marcus Eriksson commented on CASSANDRA-8497:
--------------------------------------------

agreed, even for repaired data we still keep the tombstones around for at least gcgs

> If somehow we have commit log records around since prior to a repair was completed, and
we have repair-aware tombstone collection, then we could potentially reintroduce deleted data.
Since we consider repaired data to be completely up-to-date, unless there has been a cross-cluster
failure where data only ended up in the commit log, the commit log records will by now be
superfluous. Some grace period may be necessary, as with CASSANDRA-6434.
