> While thinking about [~slebresne]'s proposal in CASSANDRA-13910, I found myself wondering
if we shouldn't also change the read repair behaviour to never work on data that already has
been repaired by anti-entropy repair before. Any mismatches on already repaired data could
as well be caused by a bug (see CASSANDRA-13004) and writing the data back again will probably
do more harm than good.
