Is there any plan to support custom markdown directives?

[tonyalaribe]

I have a usecase where we need to support markdown directives. Is there support for this? Or is it something I could contribute?

This is what I mean:
https://talk.commonmark.org/t/generic-directives-plugins-syntax/444

The idea being that we could define and plug in this new directives into the AST and define custom renderers for it.

*nod* I've been working around this by using custom HTML tags and running a second pass over the output using quick-xml, configured to allow unbalanced tags.

In the short term they will not be supported. In the long term I would like to have an interface for pluggable rules from other crates, and this could be implemented in another crate.
