It's called CommonMark because Gruber insisted. Not because extensions to markdown aren't Markdown®, which no one cares about, and not because it isn't markdown in the ways that matter. Ironically, his objection was to the idea of a single and rigorous standard, you'll note that Git-flavored markdown never drew his wrath. And yet you're treating him and Swartz's implementation as if it was such a standard. Which it is not.
