request.getAttribute in Sightly expression

I have a site where we're setting some request attributes that are used across the whole page via a JS-use file:

// requestAttributes.js

use(function(){

    request.setAttribute('testAttribute","test attribute value");

});

And sightly markup that looks like this

<sly data-sly-use.atts="requestAttributes.js">

    <html>

        <sly data-sly-include="head.html" data-sly-unwrap/>

        <sly data-sly-include="body.html" data-sly-unwrap/>

        <sly data-sly-include="footer.html" data-sly-unwrap/>

    </html>

</sly>

Is there a way to access the request attributes natively in Sightly (i.e. ${request.attributes["testAttribute"]})?  I know that I could write a second js-use file to act as a getter for retrieving the attribute value, but ideally I'd like to do access it straight from the markup rather than having data-sly-use files in all of my include files.

Thanks!
