    Should we document this configuration at 
https://github.com/apache/spark/blob/master/docs/spark-standalone.md ?
    
    I can't imagine a great reason for users wanting to disable this and 
believe that this is functioning primarily as a feature-flag to give us an 
escape-hatch in case of regressions, so maybe it's not a huge deal to leave it 
undocumented?
