I have remarked something weird. Weird but not so stupid. It is possible to make an ordered task list! (1. [x] task ) It is weird because this thing is not specified in ghf’s mardown and not in pandoc’s markdown. I have tested the exportation with Pandoc to html, Word and LibreOffice. That works.
Ordered task list can be useful to manage priority.
It is so amazing !
Please, just add it in Pandoc’s Markdown specification.
It absolutely makes sense. Obsidian has supported it from the get-go. And I convinced the Obsidian Tasks plug-in developers to support it too.
So easy to support and very useful
This does seem like a useful extension, especially as unordered task lists are already supported in GitHub Flavored Markdown and ordered task lists in Obsidian.
@LilianBeug Perhaps you suggest this to the authors of the GitHub Flavored Markdown spec? Task lists are unlikely to be added to the core CommonMark spec since this was not a feature of (the original) Markdown.
Yes absolutely. I suggest to add this point in GitHub Flavored Markdown’s specification. Your shared like is right. And in addition, I suggest to add this point in Pandoc’s specification here: Pandoc User Guide
This extension is already functional in Pandoc. Just more documentation is required.
Remark: This extension is also taken in account in Zettlr.
Many many thanks 
@jgm Please, could you confirm that ordered task list is taken in account in Pandoc.
Thank you a lot.
And thank you for your gorgeous work about Pandoc and CommonMark.
