Accept Micromark config in lint options

[farnabaz]

Currently, we can extend MarkdownIt using options.markdownItPlugins, but it is not possible to pass extensions to micromark.

It would be great to provide an option to pass Micromark extensions and configs to extend it

I was wondering when this might come up. :)

I’d prefer not to support custom micromark plugins if I don’t have to because that adds complexity and maintenance overhead and is tied to a specific parser. I don’t see significant use of markdownItPlugins across all of GitHub (see query below), and have been taking the approach of incorporating common micromark extensions by default.

What is your scenario? What micromark extension are you looking to add?

Here’s a quick GitHub query I did to filters out clones and forks of my code:

As far as I can tell, there’s just one repo that MIGHT be using this feature (and I don’t see evidence it actually is):
