The following RFC which sketches out a system for registration of markdown variants is much more interesting:

https://tools.ietf.org/html/rfc7764

Maybe, eventually, I'll be able to open a markdown textarea on a new website and be able to predict what markup will actually work!

Yep, but I can't remember the difference between Chrome Markdown, Firefox Markdown and Edge Markdown. - me, in the future. I have a hard enough time with GitHub Markdown and Reddit Markdown, as it is.

That was a jab at browsers and their history of not supporting specs identically. HTML5 is also a "strongly defined" specification and it didn't help.

Looks like fenced blocks are part of the spec - will you be adding them to SO?

Perhaps what we need is a registry in which we can store (functional) descriptions for converting markdown variants to e.g. HTML and back.

Yea! Great read.
