If you want to submit a big document for parsing make it LaTeX or HTML.

Markdown is not for that and the exact reason to use it is that every site could customize it for their usage. Contrary to your assertions (which I see is backed by no argument) abiguity in markdown is a feature. Ambiguity in HTML was a bug.

Funny, I had a blast writing a 30 page report with R Markdown, which is extended to hell and back (Math support, tables, graphics, whatnot).
