If the request is initiated due to a hint, the UA will process it using all
the same logic, which includes appending the appropriate cookies, applying
appropriate security policies, and so on.

If the concern is that you must first execute JS to manipulate/update your
cookies before the request goes out, then you already have to hide your
resources from the doc parser + preloader (which creates its own set of
performance problems), but you can still inject the hints dynamically via
JS: https://igrigorik.github.io/resource-hints/#dynamic-scheduling
