Avoid duplicating keyword and description metatags

Thanks for a great theme! It is my base theme of choice by far
In the Blueprint template.php, the theme currently respects the pagetitle module before handling the tag with sensible defaults. Could a similar check for nodewords be added before handling defaults for the metakeywords and description tags? I have taken to putting

if (module_exists('nodewords')) {
     unset($vars['meta']);
    }

in my subtheme template.php in preprocess_page to avoid doubling these up. I know you can't account for every module! So maybe a user configurable check box so that these great defaults can be switched off if some other module is addressing them?
Eager for the latest version!!
