Using Early Hints only for "entire page" requests via Cloudflare Wordpress Plugin

Cloudflare already has a Wordpress Plugin.

We know that Early Hints pre-delivers resources:

… but it only works well if you request an entire web page e.g.

You don’t want to use Early Hints if just a single asset in that website is being requested, like this:

So my question is - since Wordpress already knows what a “whole page request” looks like - can Cloudflare integrate Early Hints only on whole page requests within the Cloudflare Wordpress Plugin (a “whole page” will contain underlying assets like CSS and JS to pre-deliver) vs. every other request that’s probably just for individual assets?

The above is the implementation detail of this great idea that confuses me.
