Need Consistent Way to Test for Template Existance

Hey,
    I've been working to keep Active Scaffold up to date and one of the most common issues is that there is no consistent way to test that a template exists. At the moment I'm creating a new template with the name I want and then catching the no template exception just to check. We need functionality like this to be able to gracefully fail templates over from user customized ones to the defaults delivered with Active Scaffold.
    I'm wondering the best way to go about requesting that some feature like this is added to the standard "API" of the view logic?

Thanks,
