There's definitely a real use case where you want to do parent selection on
a different (normalized) URL that e.g. the pristine URL or cache key URL. Doing
parent selection on the cache key URL would be a benefit (think of e.g. URLs
with signatures, where you don't want the parent selection to include that
signature).
