Out of band recording of this information (using HTTP headers like:

   Link: <>; rel="related",
         <>; rel="related"

...) is quite possible whatever the format of the document.

Anyway, your arguments seem more directed towards the use of X-Pingback on
documents other than blogs, rather than towards X-Pingback itself. Are you
against the header itself, despite its advantages? (Easy parsing, no need
to get more than the head of the document, and its possible applicability
to blogs in non-HTML formats.)
