As I always understood it, “the point” of Markdown was to have a (very) simple “plain text” format that you could scan/read easily without putting it through a parser. Because it was plain text. Right?
A Markdown-formatted document should be publishable as-is, as plain text, without looking like it’s been marked up with tags or formatting instructions. [source]
And in that respect, there should be no need to standardize.
On the other hand, Markdown is so widely used that it’d be nice if there were some consensus around how to “do” certain things with/in it. That being said, aren’t most of the “problems” just a result of trying to do complicated things?
