The whole "markdown isn't standardised" point is just bullshit. Any place that supports markdown will support the basics and some places having extra features is a good thing! The only thing worse than not having a feature you need in some app is not having that feature in any app.
And the differences that exist between implementations are there for a reason. Do you think chat apps would let you have headings or footnotes or whatever if they used org mode syntax? No, they don't want to give you those formatting options, so if they used org mode instead of Markdown, they'd just rip it out of there too. And now you have the same problem.
