## Title

    [Weaviate Python v4] WeaviateUnsupportedFeatureError "<feature> is not supported by your connected server's Weaviate version"

## Body

    Cause (Documented platform behavior): The v4 client checks the connected server version before using features the server does not support.
    
    Fix status: documented_behavior
