   I was experimenting with the `hint_preload_subresources` filter on the PageSpeed example pages. In some cases, it would generate a `<Link>` header to resources with _rewritten URLs_. Unsure if this is intended behaviour, cross-linking to apache/incubator-pagespeed-mod#1756.
   But this shows that the filter is capable of hinting resources after they are rewritten.
   
   > When optimizations done by other filters expire, hints for optimizing those resources will not be generated (as it is unknown whether they'll get re-optimized at the point the HTTP headers are generated).
   
   If this is the case, is it possible to push all hinted resources, as the hints are only generated for resources that have completed their optimizations?
