No, after having checked, you are right, the default is false and it
is a bug (literally a bug, the default is true in the code, but it
doesn't get applied correctly and it end up defaulting to false
uniquely because it is the default value of a boolean in java --
https://issues.apache.org/jira/browse/CASSANDRA-2835). That bug will
be fixed in 0.8.2.

I sincerely apologize about that, you have to explicitly set
replicate_on_write to true for now. The rest stays true.
