It looks like the history of the flag begins in Cassandra's https://issues.apache.org/jira/browse/CASSANDRA-7327 where it is introduced to speedup tests by not needing to start the gossiper. The thing is we always start gossiper in our cql tests, so the flag only introduce noise. And, of course, since we want to move schema to use raft it goes against the nature of the raft to be able to apply modification only locally, so we better get rid of the capability ASAP. Tests: units(dev, debug) Message-Id: <20201230111101.4037543-2-gleb@scylladb.com>
