-// Determine which routes we want to load so we can add a `?_routes` search param
-// for fine-grained revalidation if necessary. There's some nuance to this decision:
-//
-//  - The presence of `shouldRevalidate` and `clientLoader` functions are the only
-//    way to trigger fine-grained single fetch loader calls.  without either of
-//    these on the route matches we just always ask for the full `.data` request.
-//  - If any routes have a `shouldRevalidate` or `clientLoader` then we do a
-//    comparison of the routes we matched and the routes we're aiming to load
-//  - If they don't match up, then we add the `_routes` param or fine-grained
-//    loading
-//  - This is used by the single fetch implementation above and by the
-//    `<PrefetchPageLinksImpl>` component so we can prefetch routes using the
-//    same logic
