Because some other proposals do, or could, require a per-page nonce.
After looking through this thread, I side with Robert: we should reject
the remainder of this patch. It gives up page layout flexibility that
we might want back someday. Moreover, I didn't see any hard evidence
offered that there's any actual performance gain, let alone such a
compelling gain that we should give up that flexibility for it.
