Embed markdown in pdf

[setop]

Hi,

Draw.io has this really cool feature : you can embed diagram (xml) in PNG or SVG as a comment.

That way, people who don't have the software can at least display the diagram or insert it in an office document. And people who have the software can edit the drawing (file>open>foo.drawio.png) without bothering to export it again and again (there is even an auto-save feature but that is an other topic). This saves user from having two files (xml and png) that must always be in sync.

I'd like to have the same experience with Marp. I'd like to be able to save the presentation as a PDF file only, with the markdown embedded as a comment and Marp being able to open it for edition.

I know this is a huge step - especially, how to store/retrieve the images and the theme - but it will be a huge boost for the adoption. Much easier to sell to people stuck with power-point as the export phase is the most cumbersome aspect of Marp.
