Unsure if it would affect all the models, but it would affect the whole of the tool itself, running the validation.
Is using the script generator an option? The script generator does NOT run csc.exe to validate the component... only when initially generating the component. The generator is largely identical to the Code (Script) component, and I think that generator's original intent was to "replace" these components (though we still continue to support the Code (Script) component)
