If I understand correctly, the suggestion isn't about
changing definitions or semantics
but rather about replacing conformance constraints with
an informative reference to WCAG.

Hmm... I was going to explain by example, but I don't
actually see a conformance constraint corresponding
to  "Using <h1> to identify a header rather that big text."

I see:

"The h1-h6 elements and the header element are headings."

So... I suppose I don't understand the suggestion after all.
