Should also define what happens if the driver doesn't provide the version (it
can happen for older drivers or drivers that don't support that at all) and the
guardrail is enabled.

> Guardrail for client driver versions
> ------------------------------------
>
> Key: CASSANDRA-21146
> URL: https://issues.apache.org/jira/browse/CASSANDRA-21146
> Project: Apache Cassandra
> Issue Type: Improvement
> Reporter: Brad Schoening
> Priority: Normal
>
> Many application teams lag multiple years behind on Cassandra driver
> upgrades, which increases operational risk and complicates cluster upgrades
> and support. Today, there is no native mechanism to discourage or prevent
> clients from connecting with severely outdated drivers.
> Proposed New Feature
> Introduce an optional server-side guardrail that allows operators to block
> client connections using drivers older than a configured minimum version (for
> example, rejecting Java drivers earlier than 3.11.5).
> Key Characteristics
> * Disabled by default.
> * Configurable minimum supported driver version, scoped by driver type (e.g.,
> Java).
> * Intended primarily for non-production environments (dev / UAT), where
> stricter enforcement can be applied ahead of production rollouts.
> * Provides a clear, early failure signal to application teams that a driver
> upgrade is required.
> Benefits
> * Forces proactive driver upgrades before cluster upgrades.
> * Reduces risk from unsupported or poorly tested legacy drivers.
> * Improves overall fleet hygiene and operational predictability.
