> Given we may not have time to fully resolve CASSANDRA-19007 before we release
> 5.0, it would still be helpful to have, at the very minimum, a client warning
> for cases where a user filters on two or more mutable (static or regular)
> columns at consistency levels that require coordinator reconciliation. We may
> also want the option to fail these queries outright, although that need not
> be the default.
> The only art involved in this is deciding what we want to say in the
> warning/error message. It's probably reasonable to mention there that this
> only happens when we have unrepaired data. It's also worth noting that SAI
> queries are no longer vulnerable to this after the resolution of
> CASSANDRA-19018.
