Ability to cache loader data via RequestInit['cache'] for SSG sites

[jakubszpil]

I think that adding the ability to cache or choose how to cache loaderData can significantly increase the speed of moving around a static page (SSG).

Setting the query parameter (timestamp) together with setting the cache in RequestInit from FetchAPI to 'force-cache' will make the page visitor have the data loaded faster.

For example,
instead of calling: /about.data
requested page woul call: /about.data?timestamp=1234 with { cache: 'force-cache' }
fetch('/about.data?timestamp=1234', { cache: 'force-cache' })

Is there currently a way to achieve this behavior without clientLoader (to handle prefetching also)? Or are there any plans for something like this?
