Autoexport - method for accessing (relative) url for exported page(s) from template

if you are trying to write a template for use with the AutoExport plugin, and you need access to the exported URL of an arbitrary AbstractPage (ie: the current page, or any of it's children) for any reason (in my current situation: to pass as a query param in an ifram for an external service) there is no way to do this (from the template):
$page.urlPath (java: AbstractPage.getUrlPath()) is the pre-exported path in confluence
$autoexport.link($page) (java: ExportUtils.link(AbstractPage)) generates an <a href=""/> for the page, still using the pre-exported path
ExportBeautifier will look for html nodes with "href" and "src" attributes and convert the paths, but it won't look for paths in arbitrary text (ie: script bodies, escaped in iframe params, etc...)
It would be helpful if some object was made available in the VelocityContext that had a simple method for retrieving the final exported (relative) url of an arbitrary AbstractPage as a String, which could then be included in the response as is (or if necessary for passing as an argument in some other url, escaped using $generalUtil.urlEncode())
