Hello - I'm writing an app that needs to interoperate with Obsidian's "Markdown" format, which means that this:

abc

def
ghi

needs to turn into this

<p>abc</p>
<p></p>
<p>def</p>
<p>ghi</p>

I've seen the discussion at https://github.com/orgs/syntax-tree/discussions/33 about why Markdown does not support this, unfortunately I am compelled to offer support for what Obsidian does. If anyone cares to help me on my way to perdition, I was wondering whether the following approach would work:

1. When parsing Markdown, replace '\n\n' with '\n:::blank\n' or some other custom directive that I can turn into a blank paragraph in my app
2. When producing Markdown, emit :::blank for empty paragraphs, and then replace :::blank with \n in the produced Markdown
