I like Markdown as is from a writing perspective. I wrote a recursive descent Markdown parser for a project recently, and I quickly realized how painfully ambiguous Markdown is. Lists (specifically nested lists) are the worst offenders.

Despite CommonMark, I find that many common Markdown parsers tend to "do it their own way" when it comes to edge cases. So I like this. This seems less ambiguous and easier to parse. But I don't think I'm going to be switching from regular Markdown anytime soon.
