    So a fundamental question would first be: "How
    does ENSURE-CLASS treat non-standard options in its arguments that
    specify slot or class options?"   A typical answer could be something 
    like "implementations are free to extend ...".  Or, these options might
    even be specified to be passed along to the required initialization
    methods that ENSURE-CLASS would call [see my previous note about the
    good steps taken in this direction by the the "Rainy Day" PCL.]

Quite right.
