I'm sorry. You're starting a totally different topic here.

I tried to emphasize in my article that this is about orgdown, the syntax of Org-mode which itself is an Elisp implementation of a flexible tool.

So whenever you refer to tools like Sharepoint, Confluence, Jira, ... you're discussing tools and not lightweight markup languages and where Markdown has downsides nobody seems to know of which was the goal of my article.
