Hmm, thank you for doing this. However, I'm not sure that HTML should be the defining place in the ecosystem for the concept of early hints.

In fact, I don't think the <dfn> in HTML is adding much. It is only referenced in one place, from a non-normative note. It might be better to remove the <dfn>, and change that reference to just be an <a href=""> pointing to the "Early hints" section header.

For the purpose of resource timing, probably they should reference https://httpwg.org/specs/rfc8297.html instead?

Thanks! Yes the reference you pointed out is better.

Do you want the change you mentioned to happen? I can update his PR to replace the <dfn> with <a href="">
Cheers.
