Or use pandoc[0] to convert a markdown file to an HTML file (and many other file types)

Markdown is plain text, with conventions. To lose the ability ti see your data would requiring us to lose utf8 encoding which is unlikely as it is self perpetuating.

Maybe many people on HN can do this. A lot fewer people than that on HN want to do it. And many people who use Markdown outside of HN can't do it.

Realistically, only a few people have to do it and open source a toolkit. Also I don’t really think that we’ll have that issue with markdown because it’s widespread and rather well established. This doesn’t invalidate your point, which I absolutely agree with.

Also it’s not true for the file format for canvas which is probably way harder to parse correctly.

Way harder means what? An extra 3 days of effort to the future open source Obsidian clone?
