Since Resource-Hints has been archived and now points to HTML, it's not clear to me if dynamically inserted <link rel="prefetch"> are supposed to work or if only the ones in the initial parsing would? It used to be explicitly stated

The resource hint link's [...] MAY be dynamically added to and removed from the document.

It was even one of the use-cases in that document.

Did I just miss where the current specs would allow that? I was hoping for allowed in body to say something related but even looking at that I didn't find anything conclusive.
