Sorry you are misreading and misstating what I said - markdown is a language and can of course be improved as many flavors / dialects / extensions and so on proof. Evolution is usually way better in finding conventions than your top-down Docbook in Ascii (Asciidoc) flavor. Again (re)read the post above and tell me how the Asciidoc ordered list using . and .. is more readable or the heading level 3 or 4 using ^^ or ++ and so on.
